"He did; he's no more mad than I am; but he thought it was safer to pretend being crazy. His songs was awful," said Mrs. Grix, shuddering.
"Did Miss Wedderburn know the truth?"
"Of course, sir! And when she knowed as I knowed, she tole me to 'old my tongue, and paid me for doing it; but she didn't give much, lovey!"
"Did Mr. Ferris know?"
"Seeing as Mr. Dean's his own born father--which I knowed fro' listening to 'm talking--he did."
"Did Dean kill Miss Gilmar?"
Mrs. Grix did not reply to this question with her former glibness. "I don't rightly know of that," she said slowly. "If he did, it wasn't here, for Miss Ellen was in London this long time."
"Was Dean ever in London while he stayed here under the name of Martin?"
"Yes, he was. And just about the time of the murder. It was in July Miss Ellen died, wasn't it?"
