style="font-size:15px;"> "Oh, is there another entrance?"
"Yes, but it can't be used, 'cept by people on foot. The big gates are always locked, and the road has been grassed over, an' not so many folk know of a right of way. Of course, Mr. Robert knows."
Bates was disturbed. He expected to be cross-examined farther, but, to his manifest relief, the ordeal was postponed. Winter and Furneaux commenced a careful scrutiny of the ground behind the rock. They struck off on different paths, but came together at a little distance.
"The trees," murmured Winter.
"Yes, when we are alone."
"Have you noticed – "
"These curious pads. They mean a lot. It's not so easy, James."
"I'm growing interested, I admit."
They rejoined the others.
"Did you tell me that only you and Police Constable Farrow visited this part of the wood?" said Furneaux to Bates.
"I don't remember tellin' you, sir, but that's the fact," said the keeper.
"Well, warn all the estate hands to keep away from this section during the next few days. You will give orders to Farrow to that effect, Inspector?"
"Yes. If they go trampling all over, you won't know where you are when it comes to a close search," was the cheerful answer. "Now, about that gun – it must be hidden somewhere in the undergrowth. The man who fired it would never dare to carry it along an open road on a fine morning like this, when everybody is astir."
"You're undoubtedly right," said Winter. "But here come assorted boots. They may help us a bit."
Tomlinson was a man of method. He and Farrow had brought two wicker baskets, such as are used in laundry work. He was rather breathless.
"House – and estate," he wheezed, pointing to each basket in turn.
"Go ahead, Furneaux," said Winter. "Because I ought to stoop, I don't."
The little man choked back some gibe; the presence of strangers enforced respect to his chief. He took a thin folding rule of aluminum from a waistcoat pocket, and applied it to the most clearly defined of the three footprints. Then beginning at the "house" basket, he ran over the contents rapidly. One pair of boots he set aside. After testing the "estate" basket without success, he seized one of the selected pair, and pressed it into the earth close to an original print. He looked up at Tomlinson, who was in a violent perspiration.
"Whose boot is this?" he asked.
"God help us, sir, it's Mr. Robert's!" said Tomlinson in an agonized tone.
The Inspector, Farrow and Bates were visibly thrilled; but Furneaux only sank back on his heels, and peered at the boot.
"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
