Wasnât on the flight.â Lila leaned against the wall and stared at her with black-marble eyes. âBut you already knew that, right?â
âOf course not.â
âLila,â said Tâai, âI believe her. I mean, look at her. She couldnât hurt a fly.â
You might be surprised , Nicki said to herself.
âWeâve contacted everyone he knew in the States,â added Tâai, âbut he has vanished without a trace.â
âHeâs from the States?â asked Nicki.
âHe recently retired as a professor in the department of nuclear engineering at the Massachusetts Institute of Technology. He was coming to Toronto to meet someone, and to stay with us for a while.â
âNow itâs time to spill the beans.â Lila moved three steps closer to Nicki. Then she turned to her grandson. âShe knows something.â
Nicki glanced through the curtains at the redhead. He was wandering around, picking things up, squeezing them, putting them back down againâas if he was in the produce section of a supermarket.
âWell?â prompted Lila.
âA friend of mine was sent to the hospital,â explained Nicki, âand in his pocket was a slip of paper with Robert A-G and your phone number written on it. Thatâs it. Really.â
âWhat friend?â
âWhat does it matter?â Nicki shook her head in frustration.
Lila turned to Tâai. âI still say sheâs a spy. An agent for the Peopleâs Republic of China.â
âI doubt it,â said Tâai. âI believe her. You can see sheâs upset about her friend, Lila.â
Nicki couldnât keep her eyes off the redhead. He strolled around aimlessly, finally wending his way to the cash register.
She couldnât be certain, because he was slightly out of her sight line, but Nicki was pretty sure he helped himself to some money.
âCome in here, Mac,â said Tâai.
The young manâs eyes were red and puffy and his complexion pale.
âMacâs a genius,â said Tâai. âLike my uncle.â
âSo Iâm a student at the University of Toronto in telecommunications engineering,â Mac said. âBig deal.â
âIâm a history major.â Tâai pulled out a chair and sat down. The others followed suit. âTo me, anyone who can do what Mac does is brilliant. Whatâs that youâre working on with your professor? Photonic crystals?â
âPhotonic crystals?â asked Nicki.
âItâs top secret,â said Tâai. âItâs going to change the whole smartphone industry. Explain it to her, Mac. I mean, the stuff you can talk about.â
âPhotonic technology uses light instead of electricity, so signals can be sent at extremely high speeds,â he answered. âThereâs nothing secret about that.â
âYeah, but your professorâs research is going to take the whole telecom industry by surprise,â added Tâai. âAnd it will be used in medicine and aviationâright, Mac?â
Mac nodded.
Nicki noticed Macâs fingernails. Theyâd been chewed so far down, they were bleeding.
âSo youâve discovered a method of sending signalsâdifferently? Faster?â she asked him.
âMy professor has found a way to couple resonant cavities with emitters to controllably produce photons with telecommunications wavelengths.â
Lila rolled her eyes.
âI donât know what heâs talking about half the time,â admitted Tâai, âbut itâs cutting-edge stuff.â
Nobody said anything for a minute or two, then Tâai spoke up.
âMy friend here does have a nameâDuncan MacDonald,â continued Tâai, pointing to his left. âYou know Lila and Iâm Tâai.â He scratched his chin. âSo who are you?â
âIâm Fu Yin.â
âAnd this friend you
