The Double Traitor (Paperback)

It is an easy task, Selingman declared. "This young man is your slave. Whatever your daily business may be here, some part of your time, I imagine, will be spent in his company. Let me know what manner of man he is. Is this innate corruptness which brings him so easily to the bait, or is it the stinging smart of injustice from which he may well be suffering? Or, failing these, has he dared to set his wits against mine, to play the double traitor? If even a suspicion of this should come to you, there must be an end of Mr. Francis Norgate."
