CHAPTER X
In accordance with Merrington's instructions, Caldew devoted a considerable portion of the morning seeking information among the moat-house guests. But few of them showed any inclination to talk about the murder. Many of the women were too upset to be seen, and the men had plainly no desire to be mixed up in such a terrible affair by giving interviews to detectives. Everybody was anxious to get away as speedily as possible, and Caldew was compelled to pursue his inquiries amongst groups of hurrying people, flustered servants, and village conveyances laden with luggage. Most of the departing guests replied to his questions as briefly as possible, and gave their London addresses with obvious reluctance; the few who were willing to aid the cause of justice could throw very little light on the London life of the murdered girl. Even those who had been acquainted with her before her marriage seemed to know very little about her.
Caldew finished his inquiries by midday. By that time most of the guests had departed from the moat-house and were on their way to London. Superintendent Merrington and Captain Stanhill were in the library examining the servants. Sergeant Lumbe had gone by train to Tibblestone to sift the story of the suspicious stranger who had descended on that remote village during the previous night.
It wanted an hour to lunch-time, and Caldew decided to spend the time by making a few investigations on his own account before cycling over to Chidelham in the afternoon to see the Weynes.
Caldew had not been impressed with Merrington's handling of the case. Subordinates rarely are impressed with the qualities of those placed over them in authority. They generally imagine they could do better if they had the same opportunities. Caldew was no exception to that rule. It seemed to him that Merrington lacked finesse, and was out of touch with modern methods of criminal investigation. He had been spoilt by too much success, by too much newspaper flattery, by too many jaunts with Royalty. No man could act as sheep-dog for Royalty and retain skill as a detective. That kind of professional work was fatal for the intelligence. Merrington had a great reputation behind him, and his knowledge of European criminals was probably unequalled, but his methods of investigating the moat-house murder suggested that he was no longer one of the world's greatest detectives, if, indeed, he had ever deserved recognition in their ranks. Caldew recalled that his fame rested chiefly on his wide experience rather than on the more subtle deductive methods of modern criminology. It was said in Scotland Yard that when Merrington was at the height of his reputation, twenty years before, his knowledge of London criminals and their methods was so extensive that he could in most cases identify the criminal by merely looking at his handiwork.
As a modern criminologist, Caldew believed that the less a detective intruded his own personality into his investigations the better for his chances of success. He did not think that the loud officialism of Merrington was likely to solve such a deep, subtle crime as the murder of Violet Heredith, and, consequently, he had the chance for which he had waited so long. It now remained for him to prove that he could do better than Merrington. He had sufficient confidence in his own abilities to welcome the opportunity, but at the same time he believed that he was confronted with a crime which would tax all his resources as a detective to unravel.
Like Merrington, he had been struck by the strangeness of the murder. All the circumstances were unusual, and quite outside his previous experience of big crimes. He had also come to the conclusion that the ease with which the murderer had found his way into the moat-house, and afterwards escaped, pointed to an intimate knowledge of the place.
It would be too much to say that Caldew and Merrington reached different conclusions by the same road. Up to a certain point their independent deductions from the more obvious facts of the case were alike, as was inevitable. In every crime there are circumstances and events which are as finger-posts, pointing the one way to the experienced observer. But their subsequent deductions from the outstanding facts branched widely, perhaps because the younger detective did not read so much into circumstances as Merrington. From the same facts they had reached different theories about the murder. Merrington, by a process of minute and careful deductions which he had placed before the Chief Constable, had convinced himself that the key to the murder and the murderer was to be found in London; Caldew believed that the solution of the mystery lay near the scene of the events, and perhaps in the house where the murder was committed.
Caldew was aware that he could have given no satisfactory reason for holding that belief, apart from the point that the murder had been committed by somebody who knew the moat-house sufficiently well to get in and out of the place without being seen. But that point was open to the explanation that the criminal might have provided himself with a plan of the house. Nevertheless, the impression had entered his mind so strongly that he could not have shaken it off if he had tried. But he did not try. He had sufficient imagination to be aware that intuition, in crime detection, is sometimes worth more than the most elaborate deductions.
For the rest, all his speculations about the crime were affected by the trinket he had found in the bedroom on the night of the murder. But the discovery and subsequent disappearance of that clue, as he believed it to be, had not led him very far as yet. He felt himself in the position of a palæontologist who is called upon to reproduce the structure of an extinct prehistoric animal from a footprint in sandstone. The vanished trinket was a starting-point, and no more. It was a possible hypothesis that the person who had dropped the stone and entered the death-chamber in search of it was the murderer, but so far it was incapable of demonstration or proof. As an isolated fact, it was useless, and brought him no nearer the solution of the mystery. But, on the other hand, it was an undoubted fact, and, for that reason, was dependent upon other facts for its existence. It was his task to find out who had dropped the trinket in the bedroom and subsequently returned for it during his own brief absence downstairs. To establish those essential kindred facts was, he believed, to lay hands on the murderer of Violet Heredith.
