"That's all right, old fellow," he declared. "It don't matter a snap of the fingers. That chap Brodie does get me, though. A baby could see through him. He's got just sense enough to believe that we pinched the diamond--that's why he's been round here. It just don't matter a damn, Aaron, what he suspects. That diamond doesn't exist any longer. Neither our friends whom we--er--relieved of its incriminating possession, nor Paul Brodie, will ever see that stone again. Let's lunch." Aaron Rodd reached for his hat and followed his friend out into the street. At the end of the little dingy thoroughfare, as they made their way up towards the Strand, Harvey Grimm paused abruptly in front of what seemed to be a small book-shop. There were only one or two volumes in the window, of what seemed to be editions de luxe of some unknown work. There was a single modern engraving and a water-colour of Futurist propensities for background. Harvey Grimm eyed these treasures appreciatively. "This place pleases me," he announced. "It has an air of its own. We will spend a few minutes here." The two men entered and looked about them, a little bewildered by their surroundings. They seemed to have stepped into a small and feminine sitting-room, the walls of which were hung with water-colours of unusual subjects and colouring. There was a little pile of paper-covered volumes upon the table. A young lady of sombre and uncertain appearance came forward, and Harvey Grimm promptly removed his hat. "We have perhaps made a mistake?" he observed tentatively. "From the exterior appearance of your establishment, I gathered that we might possibly be able to procure here something unusual in the way of literature. In a small way I am a collector of old books." "We are entirely modern here," the young woman replied. "I can show you hand-made pottery, or the water-colours of a young Futurist artist, or I can offer you the poetical works of one or two of our most modern poets. Second-hand books or _objets d'art_ we do not deal in. We consider," she concluded, "that modernity, absolute modernity, is the proper cult." Harvey Grimm fanned himself for a moment with his hat. His companion was gazing, with his mouth a little open, at a picture upon the wall which appeared to him to represent the bursting of a ripe tomato upon a crazy landscape. "An impression of war," the young woman remarked, following his gaze. "A wonderful piece of work by a young Futurist painter." Harvey Grimm studied it for a moment through his eyeglass, and coughed. He turned back to the table and picked up a paper-covered volume. "Poetry," he murmured, "is one of my great solaces." "Have you met with the work of Stephen Cresswell?" the young woman enquired, almost solemnly. Harvey Grimm repeated the name several times. "For the moment----" he confessed.
