wait for your omnibus, hail it and get inside. I suppose you took up some passengers on the way?"
"Oh dear, yes. We were stopping every two or three minutes to take up or set down passengers; and most of them were women."
"Very well; then we may take it that when you arrived at the Mansion House, Mrs. Schallibaum was one of your inside passengers. It was a rather quaint situation, I think."
"Yes, confound her! What a couple of noodles she must have thought us!"
"No doubt. And that is the one consoling feature in the case. She will have taken us for a pair of absolute greenhorns. But to continue. Of course she traveled in your omnibus to Kensington—you ought to have gone inside on both occasions, so that you could see every one who entered and examine the inside passengers; she will have followed you to Endsley Gardens and probably noted the house you went to. Thence she will have followed you to the restaurant and may even have lunched there."
"It is quite possible," said I. "There were two rooms and they were filled principally with women."
"Then she will have followed you to Sloane Street, and, as you persisted in riding outside, she could easily take an inside place in your omnibus. As to the theatre, she must have taken it as a veritable gift of the gods; an arrangement made by you for her special convenience."
"Why?"
