Such, in its essentials, was the evidence of the butler.

The account of Mrs. Allen, the housekeeper, was, so far as it went, a corroboration of that of her fellow servant. The housekeeper’s room was rather nearer to the front of the house than the pantry in which Ames had been working. She was preparing to go to bed when the loud ringing of the bell had attracted her attention. She was a little hard of hearing. Perhaps that was why she had not heard the shot; but in any case the study was a long way off. She remembered hearing some sound which she imagined to be the slamming of a door. That was a good deal earlier—half an hour at least before the ringing of the bell. When Mr. Ames ran to the front she went with him. She saw Mr. Barker, very pale and excited, come out of the study. He intercepted Mrs. Douglas, who was coming down the stairs. He entreated her to go back, and she answered him, but what she said could not be heard.

“Take her up! Stay with her!” he had said to Mrs. Allen.

She had therefore taken her to the bedroom, and endeavoured to soothe her. She was greatly excited, trembling all over, but made no other attempt to go downstairs. She just sat in her dressing gown by her bedroom fire, with her head sunk in her hands. Mrs. Allen stayed with her most of the night. As to the other servants, they had all gone to bed, and the alarm did not reach them until just before the police arrived. They slept at the extreme back of the house, and could not possibly have heard anything.

So far the housekeeper could add nothing on cross-examination save lamentations and expressions of amazement.

Cecil Barker succeeded Mrs. Allen as a witness. As to the occurrences of the night before, he had very little to add to what he had already told the police. Personally, he was convinced that the murderer had escaped by the window. The bloodstain was conclusive, in his opinion, on that point. Besides, as the bridge was up, there was no other possible way of escaping. He could not explain what had become of the assassin or why he had not taken his bicycle, if it were indeed his. He could not possibly have been drowned in the moat, which was at no place more than three feet deep.

In his own mind he had a very definite theory about the murder. Douglas was a reticent man, and there were some chapters in his life of which he never spoke. He had emigrated to America when he was a very young man. He had prospered well, and Barker had first met him in California, where they had become partners in a successful mining claim at a place called Benito Canyon. They had done very well; but Douglas had suddenly sold out and started for England. He was a widower at that time. Barker had afterwards realized his money and come to live in London. Thus they had renewed their friendship.
