Booker shortlisted author Jill Paton Walsh returns with the second Imogen Quy mystery. Biography is usually a safe profession. Even rather sedate. But more than one biographer has found that writing about the late great mathematician Gideon Summerfield leads to a hasty retreat. Or something more deadly....

The locked library of St Agatha's College, Cambridge, houses an unrivalled and, according to certain scholars, deeply uninteresting collection of 17th-century volumes. It also contains one dead student. Tragic and accidental, of course, even if malicious gossip hints that Philip Skellow had been engaged in stealing books rather than acquiring knowledge when he'd slipped, banged his head, and bled to death overnight.  

Imogen Quy returns after a decade to solve another intriguing Cambridge mystery. Hoping to attract a generous endowment, St Agatha's College, Cambridge, invites fabulously wealthy Sir Julius Farran to dine. The evening is a disaster for everyone but Imogen Quy: Farran asks her to come and work for him. She declines, but when Farran dies, suddenly and shockingly, she has to look into it. His death left a large hole in his company accounts that could mean financial ruin for St Agatha's.

Meet Jenny Starling: travelling cook and reluctant amateur detective. Jenny Starling is catering the 21st birthday party of upper-class twins Alicia and Justin. She arrives at their parents' country house and is immediately met by the police. A young man has drowned in the pond. Was it an accident or murder? But the birthday party goes ahead. Then, just after midnight, everyone gathers for a champagne toast...and one of the guests falls down dead. The police are baffled, and there is a whole party full of suspects.
