"I don't understand why any one should feel upset because these footprints (which, by the way, were not made by this pair of boots) happen to resemble marks which may have been made by Mr. Robert Fenley," he said, apparently talking to himself. "These marks are three or four days old. Mr. Robert Fenley went away on Saturday. Today is Wednesday. He may have been here on Saturday morning. What does it matter if he was? The man who murdered his father must have been here two hours ago."

Sensation! Tomlinson mopped his forehead with a handkerchief already a wet rag; Farrow, not daring to interfere, nibbled his chin strap; Bates scowled with relief. But the Inspector, after a husky cough, spoke.

"Would you mind telling me, Mr. Furneaux, why you are so sure?" he said.

"Now, Professor Bates, you tell him," cackled Furneaux.

The keeper dropped on his knees by the side of the detective, and gazed critically at the marks.

"At this time o' year, gentlemen, things do grow wonderful," he said slowly. "In this sort o' ground, where there's wet an' shade, there's a kind o' constant movement. This here new print is clean, an' the broken grass an' crushed leaves haven't had time to straighten themselves, as one might say. But, in this other lot, the shoots are commencin' to perk up, an' insec's have stirred the mold. It's just the difference atween a new run for rabbits and an old 'un."

"Thank you, Bates," broke in Winter sharply. "Now, we must not waste any more time in demonstrations. Mr. Furneaux explained this thing purposely, to show the folly of jumping at conclusions. Innocent men have been hanged before today on just such evidence as this. We should deem ourselves lucky that these footprints were found so soon after the crime was committed. Tomorrow, or next day, there might have been a doubt in our minds. Luckily there is none. The man who shot Mr. Fenley this morning – " he paused; Furneaux alone appreciated his difficulty – "could not possibly have left those marks today."

It was a lame ending, but it sufficed. Four of his hearers took him to mean that the unknown, whose feet had left their impress in the soil could not have been the murderer; but Furneaux growled in French —

"You tripped badly that time, my friend. You need another cigar!"

Seemingly, he was soliloquizing, and none understood except the one person for whose benefit the sarcasm was intended.

Winter felt the spur, but because he was a really great detective it only stimulated him. Nothing more was said until the little procession reached the avenue. During their brief disappearance in the leafy depths two cars and three motor cycles had arrived at The Towers. A glance sufficed. The newspapers had heard of the murder; this was the advance guard of an army of reporters and photographers. Winter buttonholed the Inspector.

"I'll tell you the most valuable service you can render at this moment," he said. "Arrange that a constable shall mount guard at the rock till nightfall. Then place two on duty. With four men you can provide the necessary reliefs, but I want that place watched continuously, and intruders warned off till further notice. This man who happens to be here might go on duty immediately. Then you can make your plans at leisure."

Thus, by the quaint contriving of chance, Police Constable Farrow, whose stalwart form and stubborn zeal had blocked the path to the Quarry Wood since a few minutes after ten o'clock, was deputed to continue that particular duty till a comrade took his place.

His face fell when he heard that he was condemned to solitude, shut out from all the excitement of the hour, debarred even, as he imagined, from standing on the rock and watching the comings and goings at the mansion. But Winter was a kindly if far-seeing student of human nature.

"It will be a bit slow for you," he said, when the Inspector had given Farrow his orders. "But you can amuse yourself by an occasional peep at the landscape, and there is no reason why you shouldn't smoke."

Farrow saluted.

"Do you mean, sir, that I can show myself?"

"Why not? The mere fact that your presence is known will warn off priers. Remember – no one, absolutely no one except the police, is to be allowed to pass the quarry, or approach from any side within hailing distance."

"Not even from the house, sir?"

"Exactly. Mr. Fenley and Miss Manning may be told, if necessary, why you are there, and I am sure they will respect my wishes."

Farrow turned back. It was not so bad, then. These Scotland Yard fellows had chosen him for an important post, and that hint about a pipe was distinctly human. Odd thing, too, that Mr. Robert Fenley was not expected to put in an appearance, or the Superintendent would have mentioned him with the others.

On reaching the house there were evidences of disturbance. Hilton Fenley stood in the doorway, and was haranguing the newspaper men in a voice harsh with anger. This intrusion was unwarranted, illegal, impudent. He would have them expelled by force. When he caught sight of the Inspector he demanded fiercely that names and addresses should be taken, so that his solicitors might issue summonses for trespass.

All this, of course, made excellent copy, and Winter put an end to the scene by drawing the reporters aside and giving them a fairly complete account of the murder. Incidentally, he sent off the Inspector post haste on his bicycle to station a constable at each gate, and stop the coming invasion. The house telephone, too, closed the main gate effectually, so when the earliest scouts had rushed away to connect with Fleet Street order was restored.

Winter was puzzled by Fenley's display of passion. It was only to be expected that the newspapers would break out in a rash of black headlines over the murder of a prominent London financier. By hook or by crook, journalism would triumph. He had often been amazed at the extent and accuracy of news items concerning the most secret inquiries. Of course the reporters sometimes missed the heart of an intricate case. In this instance, they had never heard of the bond robbery, though the numbers of the stolen securities had been advertised widely. Moreover, he was free to admit that if every fact known to the police were published broadcast, no one would be a penny the worse; for thus far the crime was singularly lacking in motive.

Meanwhile Furneaux had fastened on to Brodie again.

"You saw me at once?" he began.

"I couldn't miss you, sir," said the chauffeur, a solid, stolid mechanic, who understood his engine and a road map thoroughly, and left the rest to Providence. "I wasn't payin' particular attention, yet I twigged you the minute you popped up."

"So it is reasonable to suppose that if any one had appeared in that same place this morning and taken steady aim at Mr. Fenley, you would have twigged him, too."

"It strikes me that way, sir."

"Did you see nothing – not even a puff of smoke? You must certainly have looked at the wood when you heard the shot."

"I did, sir. Not a leaf moved. Just a couple of pheasants flew out, and the rooks around the house kicked up such a row that I didn't know the Guv'nor was down till Harris shouted."

"Where did the pheasants fly from?"

"They kem out a bit below the rock; but they were risin' birds, an' may have started from the ground higher up."

"No birds were startled before the shot was fired?"

"Not to my knowledge, sir. But June pheasants are very tame, and they lie marvelous close. A pheasant would just as soon run as fly."

The detectives began a detailed inquiry almost at once. It covered the ground already traversed, and the only new incident happened when Hilton Fenley, at the moment repeating his evidence, was called to the telephone.

"If either of you cares to smoke there are cigars and Virginia cigarettes on the sideboard," he said. "Or, if you prefer Turkish, here are some," and he laid a gold case on the table. Furneaux grabbed it when the door had closed.

"All neurotics use Turkish cigarettes," he said solemnly. "Ah, I guessed it! A strong, vile, scented brand!"

"Sometimes, my dear Charles, you talk rubbish," sighed Winter.

"Maybe. I never think or smoke it. 'Language was given us to conceal our thoughts,' said Talleyrand. I have always admired Talleyrand, 'that rather middling bishop but very eminent knave,' as de Quincey called him. 'Cré nom! I wonder what de Quincey meant by 'middling.' A man who could keep in the front rank under the Bourbons, during the Revolution, with Napoleon, and back again under the Bourbons, and yet die in bed, must have been superhuman. St. Peter, in his stead, would have lost his napper at least four times."

Winter stirred uneasily, and gazed out across the Italian garden and park, for the detectives were again installed in the dining-room.

"What about that artist, Trenholme?" he said after a pause.

"We'll look him up. Before leaving this house I want to peep into various rooms. And there's Tomlinson. Tomlinson is a rich mine. Do leave him to me. I'll dig into him deep, and extract ore of high percentage – see if I don't."

"Do you know, Charles, I've a notion that we shall get closer to bed-rock in London than here."

Furneaux pretended to look for an invisible halo surrounding his chief's close-cropped bullet head.

"Sometimes," he said reverently, "you frighten me when you bring off a brilliant remark like that. I seem to see lightning zigzagging round Jove's dome."

Fenley returned.

"It was a call from the bank," he announced. "They have just seen the newspapers. I told them I would run up to town this afternoon."

"Then you did not telephone Bishopsgate Street earlier?" inquired Winter, permitting himself to be surprised.

"No. I had other things to bother me."

"Now, Mr. Fenley, can you tell me where your brother is?"

"I can not."

He placed a rather unnecessary emphasis on the negative. The question seemed to disturb him. Evidently, if he could consult his own wishes, he would prefer not to discuss his brother.

"I take it he has not been home since leaving here on Saturday?" persisted Winter.

"That is so."

"Had he quarreled with your father?"

"There was a dispute. Really, Mr. Winter, I must decline to go into family affairs."

"But the probability is that the more we know the less our knowledge will affect your brother."

The door opened again. Mr. Winter was wanted on the telephone. Then there happened one of those strange coincidences which Furneaux's caustic wit had christened "Winter's Yorkers," being a quaint play on the lines:

 
Now is the Winter of our discontent
Made glorious Summer by this sun of York.
 

For the Superintendent had scarcely squeezed his big body into the telephone box when he became aware of a mixup on the line; a querulous voice was saying:

"I insist on being put through. I am speaking from Mr. Fenley's bank, and it is monstrous that I should be kept waiting. I've been trying for twenty minutes – "

Buzz. The protest was squelched.

"Are you there?" came the calm accents of the Assistant Commissioner.

"Yes, sir," said Winter.

"Any progress?"

"A little. Oddly enough, you are in the nick of time to help materially. Will you ring off, and find out from the exchange who 'phoned here two minutes ago? I don't mean Fenley's Bank, which is just trying to get through. I want to know who made the preceding call, which was effective."

"I understand. Good-by."

Winter explained in the dining-room that the Assistant Commissioner was anxious for news. He had hardly finished when the footman reappeared. A call for Mr. Hilton Fenley.

"Confound the telephone," snapped Fenley. "We won't have a moment's peace all day, I suppose."

Winter winked heavily at Furneaux. He waited until Fenley's hurried footsteps across a creaking parquet floor had died away.

"This is the bank's call," he murmured. "The other was from the Lord knows who. I've put the Yard on the track. I wonder why he lied about it."

"He's a queer sort of brother, too," said Furneaux. "It strikes me he wants to put Robert in the cart."
