"Ha! check number one," she said. "And what next, Dr. Armytage?"
"That depends on what end you have in view," said he. "Is Harry's safety all?"
"Yes, but his safety must be certain," she said. "I must see that man in a criminal lunatic asylum, or in penal servitude. Harry will never be safe till he is behind bars."
"I agree with you," said Geoffrey.
Dr. Armytage left the fireplace, where he had been standing since the beginning of the interview, and sat down.
"Do you realize what that demands?" he said. "It means that Mr. Francis must be allowed to make the attempt."
"Which we have already frustrated," said Lady Oxted, pointing to the fireplace.
Dr. Armytage shook his head.
"If the idea is to catch him red-handed, that is not sufficient," he said. "Harry takes whisky and soda and salt one night, very little salt, for the drug is potent. He may or he may not notice the salt. What then? Sanders, meantime, is waiting in the plate closet. No doubt we can thus catch Sanders. But that is all."
Lady Oxted rang the bell.
