I told him it was nonsense to be jealous of Aunt Fay. Of course such a pretty, jolly woman as she, full of life and fun as a girl, was bound to be popular with men, and to flirt with them a little. There was nothing in that to make a fuss about, said I. As for Brederode (whom I had to admit knowing, since we must have been seen together) I assured Sir Alec that, if he could hear Rudolph talk in a friendly way about my aunt, he wouldn't have the slightest uneasiness. Finally I made the fiery fellow confess that Aunt Fay's last little flirtation—the most innocent in the world, like all her "affairs"—was not with Brederode but with an Englishman, an officer in some crack regiment. Sir Alec did not deny that he had scolded his wife. He said that she had "answered him back," that there had been "words" on both sides, that she had stamped her foot and thrown a bunch of roses at him—middle-aged, wet-footed roses snatched from a vase which happened to be handy. That he had called her a minx; that she had retorted with "beast"; that he had stalked out of the room and then out of the house, slamming doors as hard as he could; that when he returned, not exactly to apologize, but to make up at any price, it was to find her gone, with her maid and several boxes, leaving no address; that he had tracked her to London, and eventually—as he believed—to Paris; that while there he had seen a newspaper paragraph announcing that Lady MacNairne was traveling through Dutch waterways on a motor-boat belonging to Jonkheer Brederode; that he had taken train for Amsterdam, where he had presently discovered that "Lorelei" had been; that he had visited all hotels, hoping to find the names of the party in the visitors' book, but had not been able to discover them (luckily we hadn't put our names down, and on leaving Alb had tactfully hinted to the manager that no inquiries concerning us were to be answered); that since then all trace of "Lorelei" had been lost.

I replied that it was probably a mistake made by some journalist, and that Lady MacNairne had never been on board Brederode's boat. I was going on to say more things, when Sir Alec exclaimed, "Why, you ought to know where the boat is, and who's on board her. You and Brederode were together to-night, and——"

"We hadn't been together for ten minutes," I vowed; and kept to the strict letter of the truth, for I had been smoking alone in the garden when Brederode came back and proposed that after all we should have a stroll round the fair. It hadn't taken us ten minutes to get there from the hotel.

"I didn't ask Brederode any questions about himself after meeting him," I went on; and that also was strictly true. "But," I hurriedly added, seeing a loophole of escape, "I can look him up, if you like, and, without mentioning your name, find out whether Aunt Fay is, or ever has been, with his party, which I doubt. Don't you think, for the sake of her name and yours, that would be better than for you to seek him out and make a row, before you're sure whether there's anything to row about?"

Sir Alec reflected for a minute, which was evidently an effort, then answered that perhaps I was right. But supposing I missed Brederode, whose haste to slip away went far to prove his guilt?

I would not miss him, said I. And his disappearance proved nothing. There were those pretty Frisian girls that he—Sir Alec—had been protecting when Rudolph and I came along. Brederode had probably escorted them home, not seeing any reason why he should interrupt our conversation.

My innocent surprise on hearing that, despite their costumes, the girls were not Frisian girls, but English or American ladies he had met in Amsterdam, convinced Sir Alec that they were strangers to me. And finally the scene ended by my promising to find Brederode, who was certainly—I said—stopping in the town, whether or no he had brought a motor-boat to Leeuwarden. I was to question Brederode in a diplomatic manner, and then to report to Sir Alec, on a motor-launch he had hired in Amsterdam, as the best means of tracking down the craft for which he sought. This boat, "Wilhelmina," was now in the canal at Leeuwarden, but, for reasons intimately concerning that canal, he had taken a room for the night at a hotel recommended by his chauffeur.

Fortunate it was for us that the chauffeur did not happen to prefer our hotel; and almost equally fortunate that Sir Alec was not spending much time on board his hired vessel, for, were he lurking there, it would be difficult to slip past without being followed. He had perhaps seen "Mascotte" on entering the canal (as it appeared that he had come in only toward evening), but he had not suspected the innocent-looking little creature, with her fat chaperon, "Waterspin," of having an alias. If, however, a motor-boat attempted to glide past his in the night, he would give chase, and see us on board "Mascotte." For this reason I was delighted to hear that he was at a hotel for the night, and I advised him to go there at once, to await my coming.

"How long shall you be?" he asked impatiently.

I assured him that all I had to do might keep me an hour; but I saved a few tattered rags of conscience by evading a verbal promise to call on him at the end of that hour. So much he took for granted; and, as the things I really had to do were to get the whole party on to "Mascotte" and out of the capital of Friesland, I left my uncle-in-law without much ceremony.
