As he was about to ascend, the light of the torch brought into view that part of the pit to which he was clinging, and he noticed that the testing of the withes had torn away a portion of the leafy screen, revealing the black and slimy surface of the pit's side. Colwyn was amazed to see a small peg, with a fishing line attached to it, sticking in the bare earth thus exposed. Somebody had been down the pit and placed it there—recently, judging by the appearance of the peg, which was clean and newly cut. What was at the other end of the line, which dangled in the darkness of the pit? A better hiding place for anything valuable could not have been devised. The thin fishing line was indiscernible against the slimy side of the pit, and Colwyn realised that he would never have discovered it had it not been for the lucky accident which had exposed the peg to which the line was anchored. A place of concealment chosen at the expense of so much trouble and risk indicated something well worth concealing, and it was with a strong premonition of what was suspended down the pit that the detective, taking a firmer hold of the twining tendrils above his head, began to haul up the line. The weight at the end was slight; the line came up readily enough, foot after foot running through his hand, and then, finally, a small oblong packet, firmly fastened and knotted to the end of the line.
Colwyn examined the packet by the light of the torch. It was a man's pocket-book of black morocco leather, a large and serviceable article, thick and heavy. The detective did not need the information conveyed by the initials "R. G." stamped in silver lettering on one side, to enlighten him as to the owner of the pocket-book and what it contained.
Removing the peg from the earth, Colwyn was about to place the pocket-book and the line in his pocket, but on second thoughts he restored the peg to its former position, and endeavoured to untie the knots by which the pocket-book was fastened to the line. It was difficult to do this with one hand, but, by placing the pocket-book in his pocket, and picking at the knots one by one, he at length unfastened it from the line. He tied his own pocket-book to the end of the line, and dropped it back into the pit. He next replaced the greenery torn from the spot where the peg rested. When he had restored, as far as he could, the original appearance of the hiding place, he ascended swiftly to the surface.
The first act, on reaching the fresh air, was to examine the contents of the pocket-book. As he anticipated, it was crammed full of notes of the first Treasury issue. He did not take them out to count them; a rook, watching him curiously from the edge of the wood, warned him of the danger of human eyes.
Here, then, was the end of his investigations, and a discovery which would necessitate his departure from the inn sooner than he had anticipated. Nothing remained for him to do but to acquaint the authorities with the fresh facts he had brought to light, indicate the man to whom those facts pointed, and endeavour to see righted the monstrous act of injustice which had condemned an innocent man to the ignominy of a shameful death. The sooner that task was commenced the better. The law was swift to grasp and slow to release, and many were the formalities to be gone through before the conviction of a wrongly convicted man could be quashed, especially in a grave charge like murder. Only on the most convincing fresh evidence could the jury's verdict be upset, and none knew better than Colwyn that such evidence had not yet been obtained. But the additional facts discovered during his second visit to the inn, if not in themselves sufficient to upset the verdict against Penreath, nevertheless threw an entirely new light on the crime, which, if speedily followed up, would prove Penreath's innocence by revealing the actual murderer. The only question was whether the police would use the clues he was going to place in their hands in the manner he wished them to be used. If they didn't—but Colwyn refused to contemplate that possibility. His mind reverted to the chief constable of Norfolk. He felt he was on firm ground in believing that Mr. Cromering would act promptly once he was certain that there had been a miscarriage of justice in the Glenthorpe case.
It would be necessary to arrange his departure from the inn in such a manner as not to arouse suspicion, and also to have the pit watched in case any attempt was made to recover the money he had found that morning. Colwyn, after some consideration, decided to invoke the aid of Police Constable Queensmead. His brief association with Queensmead had convinced him that the village constable was discreet and intelligent.
It was still very early as he descended to the village and sought the constable's house. His knock at the door was not immediately answered, but after the lapse of a minute or two the door was unbolted, and the constable's face appeared. When he saw who his visitor was he asked to be excused while he put on some clothes. He was back speedily, and ushered Colwyn into the room in which he did his official business.
"Queensmead," said the detective earnestly, "I have to go to Norwich, and I want you to do something for me in my absence. I am going to tell you something in strict confidence. Fresh facts have come to light in the Glenthorpe case. You remember Mr. Glenthorpe's money, which was supposed to have been stolen by Penreath, but which was never recovered. I found it this morning down the pit where the body was thrown."
"How did you get down the pit?" asked Queensmead.
"I climbed down the creepers as far as they went. I had a rope for the rest of the descent, but it wasn't needed, for I found Mr. Glenthorpe's pocket-book suspended by a cord about ten feet down. Here it is."
