“Z. Isaacson.”

The letter bore an address in the neighbourhood of Old Broad Street, London—and was dated that day.

Philip Chater read the letter through three times, without coming any nearer to its meaning. Again, the phrase—“drawn by a Mr. Arthur Barnshaw”—was more puzzling than anything else. It was, of course, probable—indeed, almost certain—that this Mr. Arthur Barnshaw was a relative of Madge; but, if so, what relative?—and on what terms of friendship, or otherwise, had he stood with the late Dandy Chater? All these things had to be discovered.

“Under any circumstances,” said Philip to himself, “this letter helps me, and points the road that I must travel. For the time, at least, I must get out of the way; this business calls me to London—and to London I will go. The name of Isaacson has a flavour of sixty per cent. and promissory notes; but I must leave explanations to him. I wish I knew who Arthur Barnshaw is.”

Still with that dread upon him of the fearful thing in the wood, he determined not to wait until the morrow, but to start for London that night. Finding, however, that it was far too late for any train to be running, he made up his mind to press Harry into his service; and sent for him, without any further delay.

The lad made his appearance at once, and stood quietly just within the closed door of the room, waiting for his master to speak. Between the two, from this night onwards, there seemed a tacit understanding that something was not to be mentioned between them, at any time—even while there was an equally strong understanding—also unspoken—that each watched for danger, and was ready to act swiftly, if necessary.

“Harry—I am going to London. Yes—yes—I know”—as the other glanced instinctively at the clock—“it’s too late for trains; I must drive as far as possible—and walk the rest. I leave all the details to you; get the horse you think will stay best; we shall go some fifteen miles, and you can then drop me, and drive back. Quick—there is no time to be lost!”

Understanding, only too well, the necessity for quickness and for caution, Harry returned, in a very short space of time, to announce that the dog-cart was in waiting at the gate in the lane, and a bag, packed with a few necessary articles, already in it. With the servant leading the way, Philip went through a long passage he had never traversed before, and, passing through a low doorway, found himself under the stars. The two men went silently across a sort of paddock, and came out into a narrow lane, where the dog-cart stood waiting, with the horse fastened to the fence.

“I thought it best to do it myself, Master Dandy; so I sent Jim away, and did the harnessing alone,” he said.

“Quite right, Harry,” replied Philip. “Here—you’d better drive—and take the straight road for London, once we get past the village.”
