I so enjoyed this book, it had me laughing several times - Frayn's wit is scintillating. This is a story about writing, how it's done (the `trick' of the title) except it isn't a trick, not really, you either can do it or you can't, as the narrator of this tale finds out to his cost. Richard Dunnett has made a comfortable academic career as the specialist on the (female) writer JL, whose books are highly regarded - and then she agrees to come and talk to his literature students. He is amused to find that she is utterly ordinary, but later as he pursues her to the room she's been given for her stay overnight, he finds himself enraptured. The older woman (Richard is 32, JL is 43) departs and he sends an excess of flowers after her and then turns up on her London doorstep.
The whole of the narrative consists of letters in which Richard tells his Australian friend what is happening. Or rather, a version of what is happening. One learns very quickly to read between the lines, especially as Richard's attempts to advise her on her work, namely, to introduce an ironic framework into her latest novel, fails to bring them closer. Finally, Richard has to admit defeat:
"I've been watching her for more than four years, and I've seen everything. But the essential bit - the gadget that makes it all work, the crystal, the chip, the formula, the dodge, the wheeze, the scam, the flick of the wrist, the twist of the fingers, the whatever it is - *that* remains as invisible as the peacocks' tongues at her banquet."
His own ironic framework securely in place, Frayn has, with this 130pp novella exceeded all expectations. It is a small but beautiful masterpiece.
