"Yes, I do see," almost shouted Jennings, "and I'll bag the whole lot."
"What are you talking about, sir?"
"Ah, I forgot you don't know," said the detective subsiding, "I'll tell you later. But you have made a discovery, Susan. This plan shows a secret entrance into Rose Cottage."
"I know it does, sir, and I thought Miss Saxon would like to see it. I don't know what Miss Loach wanted with a secret entrance, though."
"I fancy I do," said Jennings, rolling up the plans. "Your father was a very clever man, Susan. Too clever for some people. He made this secret entrance when the new wing of the cottage was built five years ago, and those who employed him gave him arsenic by way of a reward. Tyke died of arsenic also, so they are carrying on the same game."
"Oh dear, oh dear!" wept Susan, not hearing the latter part of the sentence. "So father was poisoned after all. Who did it, sir?"
"I can't tell you that," said Jennings, becoming cautious. "You had better say nothing about this, Susan, till I give you leave. You have done Mr. Mallow a great service. These plans may lead to a discovery of the murderer."
"And then Miss Saxon will marry Mr. Mallow."
"Yes. Will you be sorry?"
"No, Mr. Jennings. I am quite satisfied with my baker."
