"I should say Hannaford gave it to him," suggested Hetherwick.
But Matherfield shook his head and put the note in his own pocket.
"That's a definite clue!" he said, with emphasis. "I can trace that!"
CHAPTER IX
THE MEDICINE BOTTLE
Hetherwick went away from the sordid atmosphere of Fligwood's Rents wondering more than ever at this new development; he continued to wonder and to speculate all the rest of that day and most of the next. That Granett's sudden death had followed on Hannaford's seemed to him a sure proof that there was more behind this mystery than anybody had so far conceived of. Personally, he had not the slightest doubt that whoever poisoned Hannaford had also poisoned Granett. And he was not at all surprised when, late in the afternoon of the day following upon that of the visit to Dorking, Matherfield walked into his chambers with a face full of news.
"I know what you're going to tell me, Matherfield," said Hetherwick, motioning his visitor to an easy chair. "The doctors have held a post-mortem on Granett, and they find that he was poisoned."
Matherfield's face fell; he was robbed of his chance of a dramatic announcement.
"Well, and that's just what I was going to tell you," he answered. "That's what they do say. Same doctors that performed the autopsy on Hannaford. Doesn't surprise you?"
