Hampstead."

This was 157 and the house was empty. After a moment's hesitation he rang
the bell at the adjoining door. A woman who had been watching him from the
front room, answered the summons at once.

"Can you tell me," he enquired, "what has become of the lady who used to
live at 157--Mrs. Willet?"

"She's moved," was the uncompromising reply.

"Do you know where to?" Quest asked eagerly.

"West Kensington--Number 17 Princes' Court Road. There was a young lady
here yesterday afternoon enquiring for her."

Quest raised his hat. It was a relief, at any rate, to have news of
Lenora.

"I am very much obliged to you, madam."

"You're welcome!" was the terse reply.

Quest gave the new address to the taxi-driver and was scarcely able to
restrain his impatience during the long drive. They pulled up at last
before a somewhat dingy-looking house. He rang the bell, which was
answered by a trim-looking little maid-servant.

"Is Mrs. Willet in?" he enquired.
