As the valet again came forward , Dr. Westlake asked , `` Were you able to learn anything concerning the strangers who were here yesterday ? '' `` Not very much , sir , '' was the reply . `` I went to the Arlington first and inquired for Mr. J. Henry Carruthers , and they told me there was no such person registered there ; but they said a man answering that description , tall and wearing dark glasses , came into the hotel last evening and took dinner and sat for an hour or so in the office reading the evening papers . He went out some time between seven and eight o'clock , and they had seen nothing more of him . '' `` Was Richard Hobson at the Arlington ? '' `` No , sir ; but I went to the Riverside , and found R. Hobson registered there . They said he came in in the forenoon and ordered a carriage for Fair Oaks .
