“It's asking a bit too much, I'm afraid. Remember it was a heavy over-dose that was given.”
“Everybody's liable to make a mistake, sir.”
“True. And I suppose you'd say that after the murder at the bungalow Silverdale awoke to the fact that the maid's evidence about the hyoscine would hang him, probably; so he went back and murdered her also.”
“It was someone well known to her who did her in, sir. That's clear enough.”
“In the meantime, you've left aside the possibility that young Hassendean may have administered the stuff. How does that strike you?”
“It's possible, sir,” the Inspector admitted cautiously. “But there's no evidence for it.”
“Oh, I shouldn't like to go so far as that,” Sir Clinton said, chaffingly. “I'll tell you what evidence there is on the point. There's Hassendean's own diary, first of all. Then there's what we found in young Hassendean's laboratory notebook.”
“But that was just some stuff about weighing potash-bulbs, whatever they may be.”
“Quite correct. That was what it was.”
“Well, I'm no chemist, sir. It's off my beat.”
