"Fame—or notoriety—sometimes comes to those who seek it least," replied the detective genially. "I assure you that article came unasked. I'm a stranger to the political art of keeping sweet with the journalists—it was a statesman, you know, who summed up gratitude as a lively sense of favours to come. Now, in this case, let us play fair, actuated by the one desire to see that justice is done. This case does not strike me as quite such a simple affair as it seems to you. You approach it with a preconceived theory to which you are determined to adhere. Your theory is plausible and convincing—to some extent—but that is all the more reason why you should examine and test every link in the chain. You cannot solve difficult points by ignoring them and, to my mind, there are some difficult and perplexing features about this case which do not altogether fit in with your theory."
"If my mind is an open book to you perhaps you'll tell me what my theory is," responded Superintendent Galloway, sourly.
"Yes; that's a fair challenge." The detective pushed back his chair, and stood with his back against the mantelpiece, with a cigar in his mouth. "Your theory in this case is that chance and opportunity have made the crime and the criminal. Chance brings this young man Ronald to this lonely Norfolk inn, and sees to it that he is allowed to remain when the landlord wants to turn him away. Chance throws him into the society of a man of culture and education, who is only too glad of the opportunity of relieving the tedium of his surroundings in this rough uncultivated place by passing a few hours in the companionship of a man of his own rank of life. Chance contrives that this gentleman shall have in his possession a large sum of money which he shows to Ronald, who is greatly in need of money. Opportunity suggests the murder, provides the weapon, and gives Ronald the next room to his intended victim in a wing of the inn occupied by nobody else.
"Your theory as to how the murder was actually committed strikes me as possible enough—up to a certain point. You think that Ronald, after waiting until everybody in the inn is likely to be asleep, steals out of his own room to the room of his victim. He finds the door locked. Chance, however, has thoughtfully provided him with a window opening on to a hillside, which enables him to climb out of his own window and into the window of the next room. He gets in, murders Mr. Glenthorpe, secures his money, and, finding the key of his bedroom under the pillow, carries the body of his victim downstairs, and outside, casting it into a deep hole some distance from the house, in the hope of preventing or retarding discovery of the crime. Through an oversight he forgets the key in the door, which he had placed in the outside before carrying off the body, intending when he returned to lock the door and carry the key away with him.
"Next morning you have the highly suspicious circumstance of the young man's hurried departure, his refusal to have his boots cleaned, the incident of the £1 note, and the unshakable fact that the footprints leading to and from the pit where the body was discovered had been made by his boots.
"As a further contributory link in the chain of evidence against Ronald, you intend to use the fact that he was turned out of the Grand Hotel, Durrington, the previous day because he couldn't pay his hotel bill, because this fact, combined with the fact that Mr. Glenthorpe showed him the money he had drawn from the bank at Heathfield, supplies a strong motive for the crime. In this connection you intend to try to establish that the Treasury note which Ronald left to pay his inn bill was one of those in Mr. Glenthorpe's possession, because it happens to be one of the First Treasury issue, printed in black and white, and all Mr. Glenthorpe's notes were of that issue, according to the murdered man's own statement. That, I take it, is the police theory of this case."
"It is," said Superintendent Galloway. "You've put it a bit more fancifully than I should, but it comes to the same thing. But what do you make out of the incident at the Grand Hotel, Durrington, yesterday morning? You were there, and saw it all. Does it seem strange to you that Ronald should have come straight to this inn and committed a murder after making that scene at the hotel? Do you think it suggests that Ronald has, well—impulses of violence, let us say?" Superintendent Galloway poured himself out another glass of old brandy and sipped it deliberately, watching the detective cautiously between the sips.
Colwyn was silent for a moment. He was quick to comprehend the double-barrelled motive which underlay the superintendent's question, and he had no intention of letting the police officer pump him for his own ends.
"Sir Henry Durwood would be better able to answer that question than I," he said.
"I asked him when we were driving over here this afternoon, but he shut up like an oyster—you know what these professional men are, with their stiff-and-starched ideas of etiquette," grumbled the superintendent.
A flicker of amusement showed in Colwyn's eyes. Really the superintendent was easily drawn, for an East Anglian countryman. "After all, it is only Sir Henry Durwood's opinion that Ronald intended violence at the Grand," he said. "Sir Henry did not give him the opportunity to carry out his intention—if he had such an intention."
"Exactly my opinion," exclaimed Superintendent Galloway, eagerly rising to the fly. "I have ascertained that Ronald's behaviour during the time he was staying at the hotel was that of an ordinary sane Englishman. The proprietor says he was quite a gentleman, with nothing eccentric or peculiar about him, and the servants say the same. They are the best judges, after all. And nobody noticed anything peculiar about him at the breakfast table except yourself and Sir Henry—and what happened? Nothing, except that he was a bit excited—and no wonder, after the young man had just been ordered to leave the hotel. Then Sir Henry grabbed hold of him and he fainted—or pretended to faint; it may have been all part of his game. Sir Henry may have thought he intended to do something or other, but no British judge would admit that as evidence for the defence. This chap Ronald is as sane as you or me, and a deep, cunning cold-blooded scoundrel to boot. If the defence try to put up a plea of insanity they'll find themselves in the wrong box. There's not a jury in the world that wouldn't hang him on the evidence against him."
This time Colwyn could not forbear smiling at the guileless way in which Superintendent Galloway had revealed the thoughts which had been passing through his mind. But his amusement was momentary, and it was in a grave, earnest tone that he replied:
"The hotel incident is a puzzling one, but I agree with you that it doesn't enter into the police case against Ronald. It is your duty to deal with the facts of the case, and if you think that Ronald committed this murder——"
"If I think that Ronald committed this murder!" Superintendent Galloway's interruption was both amazed and indignant. "I'm as certain he committed the murder as if I saw him do it with my own eyes. Did you, or anybody else, ever see a clearer case?"
"It is because the circumstantial evidence against him is so strong that I speak as I do," continued Colwyn, in the same earnest tones. "Innocent men have been hanged in England before now on circumstantial evidence. It is for that very reason that we should guard ourselves against the tendency to accept the circumstantial evidence against him as proof of his guilt, instead of examining all the facts with an open mind. We are the investigators of the circumstances: it is not for us to prejudge. That is the worst of circumstantial evidence: it tends to prejudgment, and sometimes to the ignoring of circumstances and facts which might tell in favour of the suspect, if they were examined with a more impartial eye. It is for these reasons that I am always careful to suspend judgment in cases of circumstantial evidence, and examine carefully even the smallest trifles which might tell in favour of the man to whom circumstantial evidence points.
"Have you discovered anything, since you have been at the inn, which shakes the theory that Ronald is the murderer?"
"I have come to the conclusion that the case is much more complex and puzzling than was at first supposed."
"I should like to know what makes you think that," returned Superintendent Galloway. "Up to the present I have seen nothing to shake my conviction that Ronald is the guilty man. What have you discovered that makes you think otherwise?"
"I do not go as far as that—yet. But I have come across certain things which, to my mind, need elucidation before it is possible to pronounce definitely on Ronald's guilt or innocence. To take them consecutively, let me repeat that I cannot reconcile
