“Well, we won’t say that just yet, Sir James; we must see.  And we must guard against any undue predisposition to consider the robberies in a lump.  Here we are at the lodge gate again.  Is that your gardener—­the man who left the ladder by the lawn on the first occasion you spoke of?”

Mr. Hewitt nodded in the direction of a man who was clipping a box border.

“Yes; will you ask him anything?”

“No, no; at any rate, not now.  Remember the building alterations.  I think, if there is no objection, I will look first at the room that the lady—­Mrs.——­” Hewitt looked up, inquiringly.

“My sister-in-law?  Mrs. Cazenove.  Oh, yes! you shall come to her room at once.”

“Thank you.  And I think Mrs. Cazenove had better be there.”

They alighted, and a boy from the lodge led the horse and dog-cart away.

Mrs. Cazenove was a thin and faded, but quick and energetic, lady of middle age.  She bent her head very slightly on learning Martin Hewitt’s name, and said:  “I must thank you, Mr. Hewitt, for your very prompt attention.  I need scarcely say that any help you can afford in tracing the thief who has my property—­whoever it may be—­will make me most grateful.  My room is quite ready for you to examine.”

The room was on the second floor—­the top floor at that part of the building.  Some slight confusion of small articles of dress was observable in parts of the room.

“This, I take it,” inquired Hewitt, “is exactly as it was at the time the brooch was missed?”

“Precisely,” Mrs. Cazenove answered.  “I have used another room, and put myself to some other inconveniences, to avoid any disturbance.”

Hewitt stood before the dressing-table.  “Then this is the used match,” he observed, “exactly where it was found?”

“Yes.”

“Where was the brooch?”

“I should say almost on the very same spot.  Certainly no more than a very few inches away.”

Hewitt examined the match closely.  “It is burned very little,” he remarked.  “It would appear to have gone out at once.  Could you hear it struck?”

“I heard nothing whatever; absolutely nothing.”

“If you will step into Miss Norris’ room now for a moment,” Hewitt suggested, “we will try an experiment.  Tell me if you hear matches struck, and how many.  Where is the match-stand?”

The match-stand proved to be empty, but matches were found in Miss Norris’ room, and the test was made.  Each striking could be heard distinctly, even with one of the doors pushed to.

“Both your own door and Miss Norris’ were open, I understand; the window shut and fastened inside as it is now, and nothing but the brooch was disturbed?”

“Yes, that was so.”

“Thank you, Mrs. Cazenove.  I don’t think I need trouble you any further just at present.  I think, Sir James,” Hewitt added, turning to the baronet, who was standing by the door——­“I think we will see the other room and take a walk outside the house, if you please.  I suppose, by the by, that there is no getting at the matches left behind on the first and second occasions?”
