"I've oft wondered," continued Cobcroft, "if that could ha' been his will that they were signing! But then I reflected a bit on matters. And there were two or three things that made me say naught at all--not a word. First of all, I considered it a very unlikely thing that a rich man like Mr. John Mallathorpe would make a will for himself. Second--I remembered that very soon after I'd been in his private office Marshall came out into the counting-house and gave the office lad a lot of letters and documents to take to the post--some of 'em big envelopes--and I thought that what I'd seen signed was some agreement or other that was in one of them. And third--and most important--no will was ever found in any of Mr. John Mallathorpe's drawers or safes or anywhere, though they turned things upside down at the office, and, I heard, at his house as well. Of course, you see, sir, supposing that to have been a will--why, the only two men who could possibly have proved it was were dead and gone! They were killed with him. And of course, the young people, the nephew and niece, they came in for everything--so there was an end of it. But--I've oft wondered what those papers were. One thing is certain, anyway!" concluded Cobcroft, with a grim laugh, "when those three signed 'em, they were picking up their pens for the last time!" "How long was it--after you saw the signing of those papers--that the accident occurred?" asked Collingwood. "It 'ud be twelve or fifteen minutes, as near as I can recollect," replied Cobcroft. "A few minutes after I'd left the private office, Gaukrodger came out of it, alone, and stood at the door leading into the yard, looking up at the chimney. The steeple-jack was just coming down, and his mate was waiting for him at the bottom. Gaukrodger turned back to the private office and called Mr. Mallathorpe out. All three of 'em, Mallathorpe, Gaukrodger, Marshall, went out and walked across the yard to the chimney foot. They stood there talking a bit--and then--down it came!" Collingwood thought matters over. Supposing that the document which Cobcroft spoke of as being in process of execution before him were indeed duplicate copies of a will. What could have been done with them, in the few minutes which elapsed between the signing and the catastrophe to the chimney? It was scarcely likely that John Mallathorpe would have sent them away by post. If they had been deposited in his own pocket, they would have been found when his clothing was removed and examined. If they were in the private office when the three men left it---- "You're sure the drawers, safe and so on in Mr. Mallathorpe's room were thoroughly searched--after his death?" he asked.
