Alas, for his hopes! At eleven the next morning, while they were discussing the situation, a letter was delivered to Claude by special messenger. It proved to be from Hilliston, and contained a warm invitation for Larcher to take up his abode at the Kensington Gore house. "As you may only be in London for a short period, my dear Claude," wrote his guardian, "my wife and I must see as much of you as possible." With a bitter smile Claude tossed the letter across to Tait. "You see I was right," said the latter, for the second time, after skimming the note. "Mr. Hilliston is playing a double game. He wishes to keep you under his eye, thinking that, as you trust him, you will keep him informed as to your doings, so that being forewarned he may be forearmed." "Do you really think he is my enemy, Tait?" "I am really not prepared to say," replied the little man, with some hesitation. "His behavior of yesterday struck me as suspicious. He seemed unnecessarily agitated, and moreover urged you not to see Mrs. Bezel. Perhaps he thinks she will tell you too much. Taking all these facts into consideration I cannot help thinking that Hilliston is asking you to his house for some motive in connection with our search." "But he showed me the papers." "I know that, but as I told you yesterday it was Hobson's choice with him. If he hadn't imparted the information, Mrs. Bezel would have done so. Of two evils he chose the least, and by showing you the papers proved to all outward appearance that he was your firm friend. Should you bring any charge against him, he will meet it by the very argument you have just made use of." "Good Heavens!" groaned Claude, in despair, "is everybody as treacherous as you think him to be." "A good number of people are," replied Tait suavely. "A long residence in London does not strengthen one's belief in human nature. It is a city of wild beasts,--of wolves and foxes,--who rend and betray for the gaining of their own ends. If Hilliston is what I believe him to be, we must do our best to baffle him; and so you must continue to be his friend." "How can I, if he wishes to betray me?" "Ah, you are so unsophisticated, Claude," said the hardened man of the world; "you betray your feelings too plainly. In this city it is worse than madness to wear your heart on your sleeve. If you are convinced that Hilliston bears you ill----" "I am not convinced. I can't believe any man would be so base." "Ah, bah, that is a want of experience," retorted Tait, raising his eyebrows; "I'll pick you out a dozen of my decent friends who are as base or baser than I believe them to be. Respectability is all a question of concealment nowadays, and it must be confessed that your guardian wears his mask very prettily." "But do you think he is----"
