"But his anger at Stella," I protested, "and Marilyn's remark—"'

"Miss Lamar's death was the result of a cool, unfeeling plan, not pique or anger. The same cruel, careful brain executed this second crime."

Mackay, I saw, was three-quarters convinced by Kennedy. "How do you account for the dialogue Jameson overheard?" he asked.

"Miss Loring told us that Shirley suspected some one and was watching, and would not tell her or anyone else who it was. It seems most likely to me that it is the truth, Mackay. In that case her remark means that she believes his silence in a way is responsible for Werner's death."

"Oh! If Shirley had taken you into his confidence, for instance—?"

"I might possibly have succeeded in gaining sufficient evidence for an arrest, thus averting this tragedy. But it is only a theory of mine."

I scowled. It seemed to me that Kennedy was minimizing things in a way unusual for him. I wondered if he really thought the heavy man innocent.

"It's still my belief that Shirley is guilty," I asserted.

A sound of confusion from the courtyard beneath the heavy studio windows caught Kennedy's ear and ended the colloquy. From some of those near enough to look out we received the explanation. The police had arrived, fully three-quarters of an hour after Werner's death.

"I'll get the little bottle of wine, sure," Mackay murmured, picking up the food samples he had wrapped and crowding the bulky package into a pocket.
