"Oh, of course, nobody can be in two places at once, else what would become of the alibi as an institution? But as I have said, I am only setting my facts in order. Now, you see, we get down to the servants—unless some stranger is the party wanted. Shall we go outside now?"
Lenton Croft was a large, desultory sort of house, nowhere more than three floors high, and mostly only two. It had been added to bit by bit till it zig-zagged about its site, as Sir James Norris expressed it, "like a game of dominoes." Hewitt scrutinized its external features carefully as they strolled round, and stopped some little while before the windows of the two bedrooms he had just seen from the inside. Presently they approached the stables and coach-house, where a groom was washing the wheels of the dog-cart.

"That on the ground floor is the morning-room; the other is Mr. Lloyd's—my secretary. A sort of study or sitting-room."
"Now, you will see at once, Sir James," Hewitt pursued, with an affable determination to win the baronet back to good humour, "you will see at once that if a ladder had been used in Mrs. Heath's case, anybody looking from either of these rooms would have seen it."
"Of course. The Scotland Yard man questioned everybody as to that, but nobody seemed to have been in either of the rooms when the thing occurred; at any rate, nobody saw anything."
"Still, I think I should like to look out of those windows myself; it will, at least, give me an idea of what was in view
