The Mystery of Room 75 by Fred M. White — Read

It was in vain, of course, that the police sought for some tangible clue to London's latest sensational crime. Wendover might have had a good deal to say, but, for the moment, he was hanging back. Nothing was to be gained by discussing the affairs of the Brotherhood, and there was just a possibility of the murderer being brought to justice without giving Scotland Yard the whole of the facts. It might be necessary to do so later on, but for the moment Wendover was playing his own hand. To the inspector in charge of the case he simply posed as a recent acquaintance of the dead man, but he mentioned Garcia under the name of Detmar, and was frank enough with regard to the comings and goings of the Rev. James Ogilvy. About the Brotherhood and the secret of the safe he said nothing. It seemed to him that for the present he had given the authorities enough ground for arresting Garcia, but further than this he decided not to go.

But a visit to the Ambassadors' Hotel disclosed the fact that the man who called himself Detmar had disappeared, and that nothing was known of the Rev. James Ogilvy, except the fact that he had occasionally been the guest of the sham Austrian millionaire. And it is perhaps needless to say that Crockford's Clergy List contained no such name as James Ogilvy.
