“Know anything about this?” Quest asked quickly.

“Not a thing,” the Inspector replied. “We arrived, Mrs. Rheinholdt and I, at five minutes past twelve. There was no answer to our ring. I used my pass-key and entered. This is what I found.”

Quest stood over the body of his valet for a moment. The man was obviously dead. The Inspector took his handkerchief and covered up the head. A few feet away was a heavy paper-weight.

“Killed by a blow from behind,” French remarked grimly, “with that little affair. Look here!”

They glanced down at the girl. Quest’s eyebrows came together quickly. There were two blue marks upon her throat where a man’s thumbs might have been.

“The hands again!” he muttered.

The Inspector nodded.

“Can you make anything of it?”

“Not yet,” Quest confessed. “I must think.”

The Inspector glanced at him curiously.
