There was one, at least, who determined to ascertain, if possible, what that interest was--and that was Mr. Policeman Grimley. A shrewd man by nature, a very shrewd one by experience, he drew his own deductions--and they were anything but favourable to the future security of some of the inhabitants of Foxwood. Could Karl Andinnian have seen what his morning's work had done for him, he would have been ready to sit in sackcloth and ashes, after the manner of the mourners of old. "Sir Karl's living at Foxwood Court with his young wife," ran Mr. Grimley's thoughts: "I know that much. Wherever this Salter is, it's not far from him, I'll lay. Hid in Foxwood, and no mistake! I'll get him unearthed if it costs me my place. Let's see; how shall I set about it?" As a preliminary step, he gently sounded Mr. Burtenshaw; but found he could get no help from him: it was not the detective's custom to stir in any matter without orders. Mr. Grimley then slept a night upon it, and in the morning had resolved to strike a bold stroke. Obtaining a private interview with one who was high in the force at Scotland Yard, he denounced Salter, telling of Sir Karl Andinnian's visits to Burtenshaw, and their purport. "Salter is in hiding at Foxwood, or somewhere in its neighbourhood, sir, as sure as that my name's Dick Grimley," he said. "I want him took. I don't care about the reward--and perhaps it would not be given to me in any case, seeing it was me that let the fellow go--but I want him took. He's a crafty fox, sir, mark you, though; and it will have to be gone about cautiously." "If Salter be retaken through this declaration of yours, Grimley, I daresay you'll get some of the reward," was the consoling answer. "Who knows the man? It will not do for you to go down." "No, it wouldn't," acquiesced Grimley. "He knows me; and, once he caught sight of me, he'd make off like a rat sneaking out of a sinking ship. Besides, sir, I couldn't leave that other thing Mr. Burtenshaw has in hand." "Well, Who knows Salter, I ask?" "Tatton does, sir; knows him as well as I do; but Salter does not know Tatton. Tatton would be the best man for it, too. Burtenshaw himself can't manage a case as Tatton does when it comes to personal acting." There was a little more conversation, and then Grimley withdrew, and Tatton was sent for. The grass could not be let grow under their feet in the attempt to retake that coveted prize, Philip Salter.
