"I think that there is a woman at the bottom of it as usual."

"Mrs. Boazoph?"

"No, a younger and a prettier woman than Mrs. Boazoph. We will talk of that later. In the meantime I wish to see that letter and the advertisement."

"What advertisement?"

"The one in the 'Morning Post' which upset your cousin on the fourteenth; in which drawer does he stow his letters?"

Garth went to the desk. He tried the middle drawer, but it was locked; as were the other drawers. "He used to place his papers in the middle drawer," said Garth, "but you see that it is closed."

"I thought it might be," said Fanks, producing a bunch of keys, "so I brought these with me."

"No good. No skeleton keys will open these locks. They are of special construction, and Gregory was very proud of them."

"These are the keys of the desk, Garth. They were found in the dead man's pockets; and I brought them with me, in case the drawers should be locked. I was right, it seems. And now let us make our search."

He opened the middle drawer and revealed a mass of letters all in the envelopes in which they had come.
