It was his habit every afternoon, after he had worked seven or eight hours on St. Ambrose or St. Chrysostom, to walk for a while in meditation among the roses. And this was usually one of the most productive moments of his day. But even a sincere appetite for thought, and the excitement of grave problems awaiting solution, are not always sufficient to preserve the mind of the philosopher against the petty shocks and contacts of the world. And when Mr. Rolles found General Vandeleur’s secretary, ragged and bleeding, in the company of his landlord; when he saw both change colour and seek to avoid his questions; and, above all, when the former denied his own identity with the most unmoved assurance, he speedily forgot the Saints and Fathers in the vulgar interest of curiosity. “I cannot be mistaken,” thought he. “That is Mr. Hartley beyond a doubt. How comes he in such a pickle? why does he deny his name? and what can be his business with that black-looking ruffian, my landlord?” As he was thus reflecting, another peculiar circumstance attracted his attention. The face of Mr. Raeburn appeared at a low window next the door; and, as chance directed, his eyes met those of Mr. Rolles. The nurseryman seemed disconcerted, and even alarmed; and immediately after the blind of the apartment was pulled sharply down. “This may all be very well,” reflected Mr. Rolles; “it may be all excellently well; but I confess freely that I do not think so. Suspicious, underhand, untruthful, fearful of observation—I believe upon my soul,” he thought, “the pair are plotting some disgraceful action.” The detective that there is in all of us awoke and became clamant in the bosom of Mr. Rolles; and with a brisk, eager step, that bore no resemblance to his usual gait, he proceeded to make the circuit of the garden. When he came to the scene of Harry’s escalade, his eye was at once arrested by a broken rosebush and marks of trampling on the mould. He looked up, and saw scratches on the brick, and a rag of trouser floating from a broken bottle. This, then, was the mode of entrance chosen by Mr. Raeburn’s particular friend! It was thus that General Vandeleur’s secretary came to admire a flower-garden! The young clergyman whistled softly to himself as he stooped to examine the ground. He could make out where Harry had landed from his perilous leap; he recognised the flat foot of Mr. Raeburn where it had sunk deeply in the soil as he pulled up the Secretary by the collar; nay, on a closer inspection, he seemed to distinguish the marks of groping fingers, as though something had been spilt abroad and eagerly collected. “Upon my word,” he thought, “the thing grows vastly interesting.”
