“As soon as we had your information, we procured a warrant for the arrest of both parties, and then I went straight to their flat with Inspector Badger and a sergeant. There we learned from the attendant that they were away from home and were not expected back until today about noon. We kept a watch on the premises, and this morning, about the time appointed, a man and a woman, answering to the description, arrived at the flat. We followed them in and saw them enter the lift, and we were going to get into the lift too, when the man pulled the rope, and away they went. There was nothing for us to do but run up the stairs, which we did as fast as we could race; but they got to their landing first, and we were only just in time to see them nip in and shut the door. However, it seemed that we had them safe enough, for there was no dropping out of the windows at that height; so we sent the sergeant to get a locksmith to pick the lock or force the door, while we kept on ringing the bell.
