Tamsin Okoye fled her quiet, overly involved London community for the glorious anonymity of New York City, trading a life as a pastor's dutiful daughter for a temporary corporate gig on the forty-first floor.


Eleven weeks into temping for Kieran Voss -- shipping billionaire, chronic insomniac, incapable of ending a phone call -- she has made herself indispensable to a man who finds her exhausting and can't work without her.


Then federal agents arrive at 7:52 a.m. with a grand jury subpoena. $340 million has moved out of Voss Maritime to a shell company in Tortola across fourteen forged authorisations -- and on tranche eleven, in her own handwriting, are Tamsin's initials.


She signed nine documents in forty minutes without reading them. There is no version of that which survives cross-examination.


To buy time they need a story the press will run with, so they give them one: an engagement, with rules. Thirty days to find who set the trap -- and to work out which parts of the lie they've stopped pretending about.
