men had spread out in line, "you an' me will take the likeliest line. You ought to know every spot in the covert where it's possible to aim a gun at any one stannin' on top of the steps at The Towers. There can't be many such places. Is there even one? I don't suppose the barefaced scoundrel would dare come out into the open drive. Brodie said Mr. Fenley was shot through the right side while facin' the car, so he bears out both your notion an' Mr. Trenholme's that the bullet kem from the Quarry Wood. What's your idea about it? Have you one, or are you just as much in the dark as the rest of us?"
Bates was sour-faced with perplexity. The killing of his employer was already crystallizing in his thoughts into an irrevocable thing, for the butler had lifted aside the dead man's coat and waistcoat, and this had shown him the ghastly evidences of a wound which must have been instantly fatal. Now, a shrewd if narrow intelligence was concentrated on the one tremendous question, "Who hath done this thing?" He looked so worried that the yellow dog, watching him, and quick to interpret his moods, slouched warily at heel; and Farrow, though agog with excitement, saw that his crony was ill at ease because of some twinge of fear or suspicion.
"Speak out, Jim," he urged, dropping his voice to a confidential pitch, lest one of the others might overhear. "Gimme the straight tip, if you can. It need never be known that it kem from you."
"I've a good berth here," muttered the keeper, with seeming irrelevance.
"Tell me something fresh," said Farrow, quickening with grateful memories of many a pheasant and brace of rabbits reposing a brief space in his modest larder.
"So, if I tell you things in confidence like – "
"I've heard 'em from any one but you."
Bates drew a deep breath, only to expel it fiercely between puffed lips.
"It's this way," he growled. "Mr. Robert an' the ol' man didn't hit off, an' there was a deuce of a row between 'em the other day, Saturday it was. My niece, Mary, was a-dustin' the banisters when the two kem out from breakfast, an' she heerd the Gov'nor say: 'That's my last word on the subjec'. I mean to be obeyed this time.'
"'But, look here, pater,' said Mr. Robert – he always calls his father pater, ye know – 'I reelly can't arrange matters in that offhand way. You must give me time.' 'Not another minute,' said Mr. Fenley. 'Oh, dash it all,' said Mr. Robert, 'you're enough to drive a fellow crazy. At times I almost forget that I'm your son. Some fellows would be tempted to blow their brains out, an' yours, too.'
"At that, Tomlinson broke in, an' grabbed Mr. Robert's arm, an' the Gov'nor went off in the car in a fine ol' temper. Mr. Robert left The Towers on his motor bike soon afterward, an' he hasn't been back since."
Although the fount of information temporarily ran dry, Farrow felt that there was more to come if its secret springs were tapped.
"Did Mary drop a hint as to what the row was about?" he inquired.
"She guessed it had something to do with Miss Sylvia."
"Why Miss Sylvia?"
"She an' Mr. Robert are pretty good friends, you see."
"I see." The policeman saw little, but each scrap of news might fit into its place presently.
"Is that all?" he went on. They were nearing that part of the wood where care must be exercised, and he wanted Bates to talk while in the vein.
"No, not by a long way," burst out the keeper, seemingly unable to contain any longer the deadly knowledge weighing on his conscience. "Don't you try an' hold me to it, Farrow, or I'll swear black an' blue I never said it; but I knew the ring of the shot that killed my poor ol' guv'nor. It was fired from an express rifle, an' there's on'y one of the sort in Roxton, so far as I've ever seen. An' it is, or ought to be, in Mr. Robert's sittin'-room at this very minute. There! Now you've got it. Do as you like. Get Tomlinson to talk, or anybody else, but keep me out of it – d'ye hear?"
"I hear," said Farrow, thrilling with the consciousness that when some dandy detective arrived from the "Yard," he would receive an eye-opener from a certain humble member of the Hertfordshire constabulary. Not that he quite brought himself to believe Robert Fenley his father's murderer. That was going rather far. That would, indeed, be a monstrous assumption as matters stood. But as clues the quarrel and the rifle were excellent, and Scotland Yard must recognize them in that light.
Certainly, this was an unusual case; most unusual. He was well aware of the reputation attached to Robert Fenley, the banker's younger son, who differed from his brother in every essential. Hilton was steady-going, business-like, his father's secretary and right hand in affairs, both in the bank and in matters affecting the estate. Robert, almost unmanageable as a youth, had grown into an exceedingly rapid young man about town. But Roxton folk feared Hilton and liked Robert; and local gossip had deplored Robert's wildness, which might erect an insurmountable barrier against an obviously suitable match between him and Mr. Mortimer Fenley's ward, the rich and beautiful Sylvia Manning.
These things were vivid in the policeman's mind, and he was wondering how the puzzle would explain itself in the long run, when an exclamation from Bates brought his vagrom speculations sharply back to the problem of the moment.
The keeper, of course, as Farrow had said, was making straight for the one place in the Quarry Wood which commanded a clear view of the entrance to the mansion. The two men were skirting the disused quarry, now a rabbit warren, which gave the locality its name; they followed the rising edge of the excavation, treading on a broad strip of turf, purposely freed of encroaching briers lest any wandering stranger might plunge headlong into the pit. Near the highest part of the rock wall there was a slight depression in the ground; and here, except during the height of a phenomenally dry Summer, the surface was always moist.
Bates, who was leading, had halted suddenly. He pointed to three well marked footprints.
"Who's been here, an' not so long ago, neither?" he said, darting ferret eyes now at the telltale marks and now into the quarry beneath or through the solemn aisle of trees.
"Stick in some twigs, an' let's hurry on," said Farrow. "Footprints are first rate, but they'll keep for an hour or two."
Thirty yards away, and somewhat to the right, a hump of rock formed the Mont Blanc of that tiny Alp. From its summit, and from no other part of the wood, they could see the east front of The Towers. In fact, while perched there, having climbed its shoulder with great care lest certain definite tokens of a recent intruder should be obliterated, they discovered a dusty motor car ranged between the doctor's runabout and the Fenley limousine, which had returned.
The doctor and Miss Sylvia Manning were standing on the broad mosaic which adorned the landing above the steps, standing exactly where Mortimer Fenley had stood when he was stricken to death. With them were two strangers: one tall, burly and official-looking; the other a shrunken little man, whose straw hat, short jacket, and clean-shaven face conveyed, at the distance, a curiously juvenile aspect.
Halfway down the steps were Hilton Fenley and Brodie, and all were gazing fixedly at that part of the wood where the keeper and the policeman had popped into view.
"Hello!" said Bates. "Who is that little lot?"
Clearly, he meant the big man and his diminutive companion. Farrow coughed importantly.
"That's Scotland Yard," he said.
"Who?"
"Detectives from the Yard. Mr. Hilton telephoned for 'em. An' wot's more, they're signalin' to us."
"They want us to go back," said
