"So she did, under the name of Isabella Hopkins, which may or may not be her real name. At all events, she took the rooms as Miss Hopkins and signed that name on the transfer. Mrs. Slowcomb never saw her--at least, without the mask. She was as you saw her when Mrs. Slowcomb called at the rooms, and didn't show in the lawyer's office."

"But the lawyer must have seen her?"

"Well, he did, and I went to see him. He's a stiff old buckram creature, who declined to impart anything about Miss Isabella Hopkins as he wanted to know why I wished to know; and, of course, on the face of it, you can see, Towton, that I couldn't gratify his very natural curiosity."

"But why not, if we are to catch Diabella?"

"We haven't got enough grounds to go upon," said Vernon, shaking his head. "I think it is best to let her fancy we don't suspect anything and then we may be able to capture her unawares. She's connected with The Spider, if not that gentleman himself, I am sure, and your visit and behaviour, which led to the strangling attempt, have given her a fright. But if we keep silent her suspicions will be lulled and she may reappear."

"Surely not."

"Oh, I think so. Fortune-telling is an invaluable way of learning secrets, and Diabella must be very useful to The Spider, or to herself, if she is him. She won't surrender her position without a struggle. It's too paying all round, my dear fellow."

"But she did surrender it."

"Only because she lost her head for the moment and thought you might bring the police on the scene for the assault. That would lead to unpleasant questions being asked, which might result in heaven knows what revelations. Fortune-tellers are not in good odour since the campaign of a certain halfpenny paper against them."

The Colonel leaned back in his chair, reflecting, while Vernon rose to walk up and down the room for the purpose of stretching his long legs. He lighted a cigar and went on talking lightly.
