experiments coming on?"

"Admirably, admirably," answered Allen.

At the sound of his voice the lawyer looked up quickly, then apparently
reassured he said--

"You're not looking quite the same. Been keeping yourself too much
indoors, I imagine. You ought to quit research and do some shooting
this autumn."

"I intend to, and I hope then to have your company."

"I shall be pleased to run down, although I am no great hand at a gun."

"I want to speak with you a few moments in private. Would you mind
locking the door so that we may not be interrupted?"

"We are quite safe from interruption here," said the lawyer, as he
turned the key in the lock; then resuming his seat he added, "Nothing
serious, I hope?"

"It is rather serious. Do you mind my sitting here?" asked Allen, as he
drew up his chair so that he was between Grey and the door, with the
table separating them. The lawyer was watching him with anxious face,
but without, as yet, serious apprehension.

"Now," said Allen, "will you answer me a simple question? To whom are
you talking?"
