He left her more deeply in love than ever; but there seemed no note of hope or promise in their farewell. And yet he felt a profound conviction that they would meet again. She undertook to acquaint him with her movements and was not sure that she would accept Albert Redmayne's invitation to join him. So Mark left her, believing that Doria was certain to determine her future and guessing that, if she presently proceeded to Como, the lively and indomitable Italian would quickly follow. For the present, however, Giuseppe seemed to be concerned with his own affairs. He brought Brendon back on his last journey from "Crow's Nest" in the launch and explained that he had already found good work beside the Thames. "We shall, I hope, meet again," he said, "and you may hear presently of a very wonderful adventure in which Doria shall be l'allegro--the merry man and the hero!" They talked and Mark became impatient under a growing consciousness that the quicker-witted spirit was pulling his leg. Doria preserved the best possible temper, but his Latin love of a certain sort of fun seemed cynical and almost inhuman under the circumstances. They spoke of the mystery and, upon that subject, the motor boatman declared himself as quite unable to find any explanation; but, with respect to Brendon's failure, he did not hesitate to make a sly allusion. Indeed he hinted at things which Mark was to hear six months later in a more responsible mouth. "Above all, what has puzzled me most in this horrid affair is you, Brendon," declared Giuseppe. "You are a great sleuth, we know; yet you are no better than the rest of us stupid people before these happenings and horrors. That made me wonder for a long time; but now I wonder no longer." "I'm beat and I own it. I've missed something vital--the keystone of the arch. But why do you say that you wonder no more? Because you know me now and find me a very dull dog?" "Not so, my friend, far from it. You are a very wily, clever dog. But--well, as we say in Italy, 'if you put a cat into gloves, she will not catch mice.' You have been in gloves ever since you knew Madonna was a widow." "What do you mean?" "Very well you know what I mean!" And that was the end of their conversation, for Brendon frowned in silence and Giuseppe began to slack the engines as they reached the landing stage. "Something tells me I shall meet you again, Marco," he said as they shook hands and prepared to part; and Brendon, who shared that impression strongly enough, nodded. "It may be so," he answered. For a period of several months, however, the detective was not to hear more of those who had played their small parts in the unsolved mystery. He was busy enough and in some measure rehabilitated a tarnished reputation by one brilliant achievement in his finest manner. But success did not restore his self-respect; and it diminished in no degree the fever burning at his heart.
