"Who was it?"

Carly shot out the question quickly, and immediately the board moved to T. From that, as the two breathlessly waited, the pointer very slowly spelled Thorpe.

The word did not go smoothly,—the board swung round in large loops, but paused positively at each letter, and then started slowly to the next.

"You didn't push, Kit?" Carly asked, but more from force of habit than any doubt of him.

"Of course not. Nobody could push with you watching, nor was there any reason why I should. Did you?"

"Of course not. Don't let's ask each other that. We're both honest. But you know, Kit, Mr. Crane had a communication from Peter and he said Thorpe did it. But Mr. Crane thinks maybe Peter doesn't know."

"Let's try to get Blair's spirit."

They tried,—if receptive waiting can be called trying,—and at last they succeeded in receiving the information that Gilbert Blair's spirit was present.

"Will you tell us who killed you?" Carly asked at once, fearing lest he go away.

Slowly the pointer moved away from the letter T. But after a series of swirls it stopped definitely at M.
