itâs entirely possible youâll stay through several seasonsââ
âBut weâll leave before July 1917,â Felix added quickly.
âOf course,â Great-Uncle Thorne said. âOf course.â
And unconvincingly, Felix thought.
Great-Uncle Thorne cleared his throat.
âThe point is, you need to have the proper clothing, or you could freeze to death,â Great-Uncle Thorne said.
âThis doesnât make sense,â Maisie said, narrowing her eyes at her uncle. âYouâve never ever told us where to go, or helped us get there, or anything.â
âHeâs only looking out for us,â Felix told her. âI think itâs nice.â
âBut every other time, we landed in whatever we had on and made doââ Maisie began to protest.
âThis time,â Great-Uncle Thorne boomed, banging his fist down hard on one of the desks, âyou canât just
make do
. This time, you must be prepared. For anything.â
âWhy?â Maisie asked.
âBecause this time is different,â Great-Uncle Thorne said, sinking onto the chair that was attached to the wooden desk. âThis time you will be taking the lost Fabergé egg with you. This time something is going to happen. Something wonderful.â
Great-Uncle Thorneâs eyes took on the yellow light of the lamps.
He sighed. âI wish I knew what it was. But I donât. I only know that the lost egg has been found. That Amy Pickworth has spoken to us across time and space. That
something
special, something unforgettable, is going to occur in Imperial Russia.â
Great-Uncle Thorne sighed again.
âItâs too complicated for me to explain,â he said, shaking his head. âWhy, sometimes Iâm not sure I completely understand it myself. But Phinneas called our ability to time travel and for events to happen simultaneously in different times and places the Pickworth Paradoxia Perpetuity.â
âThe Pickworth Paradoxia Perpetuity,â Felix said in a hushed voice.
âYes,â Great-Uncle Thorne said solemnly. âItâs so complex, so amazing, so . . . mind-boggling, that even I can barely understand it myself.â
Maisie and Felixâs motherâs voice cut through the heavy silence that descended after Great-Uncle Thorneâs words.
âAnother secret room?â she said, coming inside.
Right behind her came Bruce Fishbaum, looking more nautical than ever in his Nantucket-red pants and navy blue belt with little white whales, and a white shirt with some yacht club logo on it.
âThis house is huge!â Bruce Fishbaum exclaimed. His face was pink, his hairline receding even more.
âIndeed,â Great-Uncle Thorne said, his voice dripping with displeasure.
âSo this room is . . . ?â their mother asked, glancing around.
âThe Map Room,â Felix answered, since no one else was going to. âGreat-Uncle Thorne and Great-Aunt Maisie used to learn history and geography here.â
âReally?â his mother cooed. âThatâs amazing. Isnât that amazing?â she asked Bruce Fishbaum.
He laughed his guffawing laugh. âAmazing!â
âWe were just talking about Peter Carl Fabergé,â Great-Uncle Thorne said.
âWe were?â Maisie asked.
But Great-Uncle Thorne ignored her. âYouâve heard of him?â
âSure,â Bruce Fishbaum said. âHe made the fancy eggs.â
âYes,â Great-Uncle Thorne said, âhe did. Fabergé was the official court jeweler to the Tsar of Russia.â
âYou donât say,â Bruce Fishbaum said in a way that made it hard for Maisie to know if he was really interested or not.
âAt the turn of the last century, he employed over five hundred people in his St. Petersburg workshop. Of course, he designed more than the eggs. Little cases and jewelry and his miniatures of flowers and
