Here lay the real puzzle, and for some minutes I could make nothing of it. Then I remembered my telegram. According to William it had been referred back to the post office. But William on his own admission had but retailed pantry gossip caught up from Mr. Horrex (presumably the butler). Had the telegram been sent back _unopened?_ William's statement left this in doubt. Now supposing these people to be in league with Trewlove, they might have opened the telegram, and, finding to their consternation that I was already on the road and an exposure inevitable, have ordered my room to be prepared, trusting to throw themselves on my forgiveness, while Trewlove lay a-hiding or fled from vengeance across the high seas. Here was a possible explanation; but I will admit that it seemed, on second thoughts, an unlikely one. An irate landlord, returning unexpectedly and finding his house in possession of unauthorised tenants--catching them, moreover, in the act of turning it upside-down with a fancy-dress ball--would naturally begin to be nasty on the doorstep. The idea of placating him by a bedroom near the roof and the costume of a Punchinello was too bold altogether, and relied too much on his unproved fund of goodnature. Moreover, Mr. Herbert (whoever he might be) would not have treated the situation so cavalierly. At the least (and however 'irregilar'), Mr. Herbert would have been waiting to deprecate vengeance. A wild suspicion occurred to me that 'Mr. Herbert' might be another name for Trewlove, and that Trewlove under that name was gaining a short start from justice. But no: William had alluded to Mr. Herbert as to a youth sowing his wild oats. Impossible to contemplate Trewlove under this guise! Where then did Trewlove come in? Was he, perchance, 'Mr. Horrex,' the butler? I gave it up and began thoughtfully, and not without difficulty, to case myself in the disguise of Punchinello. I resolved to see this thing through. The costume had evidently not been made to my measure, and in the process of induing it I paused once or twice to speculate on the eccentricities of the figure to which it had been shaped or the abstract anatomical knowledge of the tailor who had shaped it. I declare that the hump seemed the one normal thing about it. But by this time my detective-hunger--not to call it a thirst for vengeance--was asserting itself above petty vanity. I squeezed myself into the costume; and then, clapping on the false nose, stood arrayed--as queer a figure, surely, as ever was assumed by retributive Justice.
