“You did it,” she repeated dully. “You killed him—for my sake!”
Even in the midst of the intense strain those last three words thrilled me with secret joy. Heaven forgive me for wishing for an instant that they were true. I could have brought myself to accept the terrible possibility which had been haunting me ever since the voice of Inspector Charles had told me through the telephone that Weathered was a corpse, the possibility that I had administered a fatal dose. But I saw that Violet was on the verge of breaking down. For her sake, far more than for my own, I must banish that theory from the field.
“No,” I assured her again. “That is out of the question. Sir Frank Tarleton is the greatest living authority on poisons, and he has been engaged for the last three days in trying to ascertain the cause of death. I have been by his side the whole time, assisting him, and I know that his suspicions point in another direction altogether.”
I broke off to catch her in my arms as she swayed forward. I was just in time. I laid her gently on the moss and sprinkled her face with water from the spring, the sweet face that I would have given all I possessed to sprinkle with kisses instead. Luckily the collapse was only momentary. While I was still bending over her she opened her lips to say, “Go on. Tell me everything.”
I waited till she had recovered strength enough to sit up. It would have done harm to wait longer. It was necessary for her to know exactly how matters stood.
“Dr. Weathered had other victims beside you, and other enemies beside me. The police are on the trail of some of them and Sir Frank has obtained an important clue which may lead us to the true cause of death. But meanwhile notice has been attracted to the costume in which I went to the Domino Club that night.”
Violet began to look frightened.
“The one I lent you?—you ought to have destroyed it!” she said excitedly.
“It is very fortunate I didn’t,” I returned soothingly. “It has come out that it was the costume you generally wore; and you remember that was why you lent it to me, so that Weathered should think I was you. Anyhow, it has been traced to you, and if you couldn’t produce it you would be called on to account for its disappearance. Do you see that?”
“Yes, I see that. But surely if they know the costume was mine they must believe that I was there that night. My God, do they suspect me of the murder?”
