"Quite so, sir. For that reason I have been trying to make up my mind to confide in you. When you have heard what I have to say you will understand how hard it is. It relates to Mr. Philip, sir. Since his illness I have been worried about his health, because he is so changed that I feared he might go mad with grief. He hardly speaks a word to anybody, but sometimes I have seen him muttering to himself. The night before he went away with Mr. Musard he did not come down to dinner. Miss Heredith was going to send a servant to his room in case he had not heard the gong, but I offered to go myself. When I reached his bedroom, I heard the most awful sobbing possible to imagine. Then, through the partly open door, I heard Mr. Philip call on God Almighty to make somebody suffer as he had suffered. He mentioned a name—"

"Whose name?"

The butler looked fearfully towards the closed door, as though he suspected eavesdroppers, and then brought it out with an effort:

"Captain Nepcote, sir."

Colwyn had expected that name. Nepcote's statement on the previous night had led him to believe that Philip Heredith had suspected Nepcote's relations with his wife, but could not bring himself to disclose that when he sought assistance. It was Colwyn's experience that nothing was so rare as complete frankness from people who came to him for help. It was part of the ingrained reserve of the English mind, the sensitive dread of gossip or scandal, to keep something back at such moments. The average person was so swaddled by limitations of intelligence as to be incapable of understanding that suppressed facts were bound to come to light sooner or later if they affected the matter of the partial confidence. Of course, there was sometimes the alternative of a reticence which was intended to mislead. If that entered into the present case it was an additional complication.

"What interpretation did you place on these overheard words?" he asked the butler. "Did you suppose that they referred to the murder?"

"Well, sir—" the butler hesitated, as if at a loss to express himself. "It was not for me to draw conclusions, sir, but I could not help thinking over what I had heard. I know Mr. Philip believed the young woman to be innocent, and—Mrs. Heredith was shot with Captain Nepcote's revolver."

"I see. You had no other thought in your mind?"

"No, sir. What else could I think?"

The butler's meek tones conveyed such an inflection of surprise that Colwyn was convinced that he, at all events, had no suspicion of the secret between Mrs. Heredith and Nepcote.
