"Well, I will go so far as to say that Hazel Rath is a most unlikely person to commit murder."

"Murder is an unlikely crime. There is no brand of Cain to reveal the modern murderer. Finger-prints are a surer means of identification. This unhappy girl may be the victim of one of those combinations of sinister events which sometimes occur in crime, but I do not intend to form an opinion about that until I know more about the case. For that reason I shall be glad if you will give me your account of everything that happened on the night of the murder. Philip Heredith's story is incomplete, and I wish to hear all the facts."

Musard nodded, and related the particulars with an attention to detail which left little to be desired. His version filled in the gaps of Phil's imperfect narrative, and enabled the detective to visualize the murder with greater mental distinctness. The two stories agreed in their essential particulars, but they varied in some degree in detail. Colwyn, however, was well aware that different witnesses never exactly agree in their impressions of the same event. Phil had made only an incidental reference to the dinner-table conversation about jewels, and Colwyn was not previously aware that the story of the ruby ring had occupied twenty minutes in the telling.

"How did you come to tell the story?" he asked.

"Some of the ladies were admiring my ring, and Phil suggested that they should hear the story of its discovery. I had just finished when the scream rang out from upstairs, followed by the shot."

"How long was the interval between the scream and the shot?"

"Only a few seconds," replied Musard. "Some of us started to go upstairs as soon as we heard it, but the shot followed before we reached the door of the dining-room."

Colwyn reflected that this estimate differed from Phil Heredith's, who had thought that nearly half a minute elapsed between the scream and the shot. But he knew that a correct estimate of the lapse of time is even rarer than an accurate computation of distance.

Musard knew nothing about two aspects of the case on which Colwyn desired to gain light. He had seen nothing of the target shooting in the gun-room the day before the murder, but he thought it quite possible that Captain Nepcote's revolver might have lain there unnoticed until the following night, because the men of the house party were a poor shooting lot who were not likely to use the gun-room much. He had heard the head gamekeeper say that there had been no shooting parties, and Tufnell had told him that only one or two of the men had brought guns with them. Neither was Musard aware whether there existed the motive of wronged virtue or slighted affection to arouse a girl like Hazel Rath to commit such a terrible crime. He had always thought her a sweet and modest girl, but he had seen too much of the world to place much reliance on externals, and he had had very few opportunities of observing whether there had been anything in the nature of a love affair between her and Philip. His own view was that whatever feeling existed was on the girl's side only.

"If there had been love passages between them, Phil's conscience would not have allowed him to be quite so certain of her innocence," added Musard. "I told him of her arrest, and there can be no doubt that he thinks the police have made a hideous mistake in arresting her. Detective Caldew refused to admit the possibility of mistake, but Phil shuts his eyes to everything that tells against the girl, including her mother's unpleasant past."
