“Thanks,” said Hart.

Doris, more self-possessed now, read the meaning of the quip promptly.

“Mr. Grant has often spoken of you,” she said. “You talk, and we’ll listen.”

“Not so, divinity,” came the retort. “I may be a parrot, but I don’t want my neck wrung when you’ve gone.”

“Don’t encourage him, Doris,” said Grant, “or you’ll be here till midnight.”

“If that’s the best you can do, you had better leave the recital to me,” laughed Hart.

The detective’s blood ran cold. What if Hart discovered yet another ghost?

“Robinson—go home!” he said, in sepulchral tones.
