nearly one o'clock in the morning
But I took notice of each , and then walked back in the direction whence I had come . I returned at once to the hotel , but my wife had not yet come back . This surprised me . And I was still further surprised when she did not arrive until nearly one o'clock in the morning . Yet she seemed very happy -- unusually so . Where had she been after receiving that secret message , I wondered ? Yet I could not question her , lest I should betray my watchfulness .
