"Bring him in, Johnson," said Mr. Cromering. He turned to Colwyn and added: "When I received your telegram I telephoned to Galloway and asked him to be here this afternoon. As he worked up the case against Penreath, I thought it better that he should be present and hear what you have to say. You have no objection, I suppose?" "On the contrary, I shall be very glad for Galloway to hear what I have to say." The police constable returned, ushering in Superintendent Galloway, who looked rather surprised when he saw his superior officer's visitors. He nodded briefly to Colwyn, and looked inquiringly at the chief constable. "Mr. Colwyn has discovered some fresh facts in the Glenthorpe murder, Galloway," explained Mr. Cromering. "I sent for you in order that you might hear what they are." "What sort of facts?" asked Galloway, with a quick glance at the detective. "That is what Mr. Colwyn proposes to explain to us." "I shall have to go back to the beginning of our investigations to do so--to the day when we motored from Durrington to Flegne," said the detective. "We went there with the strong presumption in our minds that Penreath was the criminal, because of suspicious facts previously known about him. He was short of money, he had concealed his right name when registering at the hotel, and his behaviour at the breakfast table the morning of his departure suggested an unbalanced temperament. It is a legal axiom that men's minds are influenced by facts previously known or believed, and we set out to investigate this case under the strong presumption that Penreath, and none other, was the murderer. "The evidence we found during our visit to the inn fitted in with this theory, and inclined the police to shut out the possibility of any alternative theory because of the number of concurrent points which fitted in with the presumption that Penreath was the murderer. There was, first, the fact that the murderer had entered through the window. Penreath had been put to sleep in the room next the murdered man, in an unoccupied part of the inn, and could easily have got from one window to the other without being seen or heard. Next was the fact that the murder had been committed with a knife with a round end. Penreath had used such a knife when dining with Mr. Glenthorpe, and that knife was afterwards missing. Next, we have him hurriedly departing from the inn soon after daybreak, refusing to wait till his boots were cleaned, and paying his bill with a Treasury note.
