“Only because Clayton appeared to fear some mishap,” Vandyke replied. “He admitted he had no definite reason for it, but he seemed very nervous.”

“Where were you when he left? You were his best man.”

“True. I came here to tell you about that.”

“About what?”

“One of the caterer’s assistants came in here a short time ago, not more than twenty minutes, and stated that Mr. Lenaire wanted to see me in the dining room.”

“Lenaire is the caterer?”

“Yes. It was upon my recommendation that he was given this job. I asked Clayton if he had any immediate use for me, and he told me to go ahead and see what Lenaire wanted. I did so and found him in the dining room.”

“What did he want?”

“He wanted to thank me again for having recommended him, and also to ask me to express his gratitude to Clayton for having seconded my suggestion, which he feared he would not have an opportunity to do personally before Clayton departed. He explained at some length, Nick, and when I returned I found that Clayton was missing. Then, when unable to find Clara, I feared something was wrong.”

“I see,” Nick nodded. “Did the waiter who came up return to the dining room with you?”
