"Where?"

"In one of the rooms at the front. We have parties in A and B."

"You go and find him," said Nick. "I want to see him right away."

Gaspard went to the front of the house. A hall branched off at right angles with that in which Nick was standing. On the second hall were three rooms, A, B and C.

Room C was next the avenue. The other two had windows on an open space between two wings of the building. Nick glanced at the register, and saw that "R.M. Clark and wife" had been assigned to room A, and "John Jones and wife" to room B. Room C was vacant.

The detective had barely time to note these entries on the book when Gaspard came running back.

His face was as white as paper, and his lips were working as if he were saying something, but not a sound came from them.

He was struck dumb with fright. Whatever it was that he had seen must have been horrible, to judge from the man's trembling limbs and distorted face.

Nick had seen people in that condition before, and he did not waste time trying to get any information out of Gaspard.

Instead, he seized the frightened fellow by the shoulder and pushed him along toward the front of the house.
