The Cardigan Gambit

By Eleanor Kross

A spreadsheet architect. A vanished flatmate. And a subterranean mystery where the numbers just don't add up...
Hannah prefers to live in the margins. It's safer there, and significantly more likely to spare her from the office tea round. As an expert in risk assessment, she finds profound comfort in the mathematical regularity of a good Excel grid.
Then her flatmate Vivi-a whirlwind of kinetic art, physics, and chaos-vanishes.
All Vivi leaves behind is a snapped lanyard, a very cold kettle, and a puzzle that defies every logical rule on Hannah's spreadsheets.
To track her down, Hannah recruits Sebastian: a wealthy intellectual who can find a soul in a pivot table, but is routinely defeated by the instructions on a box of frozen pizza. Together, the unlikely duo must follow a trail of forgotten blueprints, hidden vaults, and corporate secrets buried beneath London's streets.
Up against a shadowy adversary and an overly anxious henchman, Hannah is about to discover that the most dangerous variable in any mystery... is an auditor with a very long memory.
