Then I knew how it was done. The chambermaid, loitering about the room for a tip, was—Mrs. Quackenboss! It needed but an apron to transform her pretty travelling-dress into a chambermaid's costume; and in any of those huge American hotels one chambermaid more or less would pass in the crowd without fear of challenge.

"We will follow them on to Saratoga," Charles cried. "Pay the bill at once, Seymour."

"Certainly," I answered. "Will you give me some money?"

Charles clapped his hand to his pockets. "All, all in the dispatch-box," he murmured.

That tied us up another day, till we could get some ready cash from our agents in New York; for the manager, already most suspicious at the change of name and the accusation of theft, peremptorily refused to accept Charles's cheque, or anything else, as he phrased it, except "hard money." So we lingered on perforce at Lake George in ignoble inaction.

"Of course," I observed to my brother-in-law that evening, "Elihu Quackenboss was Colonel Clay."

"I suppose so," Charles murmured resignedly. "Everybody I meet seems to be Colonel Clay nowadays—except when I believe they are, in which case they turn out to be harmless nobodies. But who would have thought it was he after I pulled his hair out? Or after he persisted in his trick, even when I suspected him—which, he told us at Seldon, was against his first principles?"

A light dawned upon me again. But, warned by previous ebullitions, I expressed myself this time with becoming timidity. "Charles," I suggested, "may we not here again have been the slaves of a preconception? We thought Forbes-Gaskell was Colonel Clay—for no better reason than because he wore a wig. We thought Elihu Quackenboss wasn't Colonel Clay—for no better reason than because he didn't wear one. But how do we know he ever wears wigs? Isn't it possible, after all, that those hints he gave us about make-up, when he was Medhurst the detective, were framed on purpose, so as to mislead and deceive us? And isn't it possible what he said of his methods at the Seamew's island that day was similarly designed in order to hoodwink us?"

"That is so obvious, Sey," my brother-in-law observed, in a most aggrieved tone, "that I should have thought any secretary worth his salt would have arrived at it instantly."

I abstained from remarking that Charles himself had not arrived at it even now, until I told him. I thought that to say so would serve no good purpose. So I merely went on: "Well, it seems to me likely that when he came as Medhurst, with his hair cut short, he was really wearing his own natural crop, in its simplest form and of its native hue. By now it has had time to grow long and bushy. When he was David Granton, no doubt, he clipped it to an intermediate length, trimmed his beard and moustache, and dyed them all red, to a fine Scotch colour. As the Seer, again, he wore his hair much the same as Elihu's; only, to suit the character, more combed and fluffy. As the little curate, he darkened it and plastered it down. As Von Lebenstein, he shaved close, but cultivated his moustache to its utmost dimensions, and dyed it black after the Tyrolese fashion. He need never have had a wig; his own natural hair would throughout have been sufficient, allowing for intervals."
