“Won’t the description do?”
“Not as well as the original.”
“Well, I’m very sorry,” I said, as calmly as I could, “I—the thing is lost. It—it must have fallen out of a box on my dressing-table.”
Whatever he thought of my explanation, and I knew he doubted it, he made no sign. He asked me to describe the link accurately, and I did so, while he glanced at a list he took from his pocket.
“One set monogram cuff-links,” he read, “one set plain pearl links, one set cuff-links, woman’s head set with diamonds and emeralds. There is no mention of such a link as you describe, and yet, if your theory is right, Mr. Armstrong must have taken back in his cuffs one complete cuff-link, and a half, perhaps, of the other.”
The idea was new to me. If it had not been the murdered man who had entered the house that night, who had it been?
“There are a number of strange things connected with this case,” the detective went on. “Miss Gertrude Innes testified that she heard some one fumbling with the lock, that the door opened, and that almost immediately the shot was fired. Now, Miss Innes, here is the strange part of that. Mr. Armstrong had no key with him. There was no key in the lock, or on the floor. In other words, the evidence points absolutely to this: Mr. Armstrong was admitted to the house from within.”
“It is impossible,” I broke in. “Mr. Jamieson, do you know what your words imply? Do you know that you are practically accusing Gertrude Innes of admitting that man?”
“Not quite that,” he said, with his friendly smile. “In fact, Miss Innes, I am quite certain she did not. But as long as I learn only parts of the truth, from both you and her, what can I do? I know you picked up something in the flower bed: you refuse to tell me what it was. I know Miss Gertrude went back to the billiard-room to get something, she refuses to say what. You suspect what happened to the cuff-link, but you won’t tell me. So far, all I am sure of is this: I do not believe Arnold Armstrong was the midnight visitor who so alarmed you by dropping—shall we say, a golf-stick? And I believe that when he did come he was admitted by some one in the house. Who knows—it may have been—Liddy!”
I stirred my tea angrily.
