“Good evening, Dr. Ringwood,” the Chief Constable greeted him. “I think we've managed to get here at the time I promised, though it was a difficult business with all this fog about.”

He turned to introduce his companion.

“This is Inspector Flamborough, doctor. He's in charge of the case. I'm merely here as an onlooker. I've given him the facts, so far as I know them from you; but I expect that he may wish further information if you have any.”

Dr. Ringwood nodded, but seemed to hesitate for a moment before replying:
