Hannah prefers to live in the margins. It's safer there, and significantly more likely to spare her from the office tea round. A "spreadsheet architect" by trade, she treats a risk assessment as a spiritual practice and finds profound comfort in the mathematical regularity of an Excel grid.But when her flatmate Vivi-a whirlwind of kinetic art and physics-vanishes, leaving behind only a snapped lanyard and a very cold kettle, Hannah's perfectly balanced world hits a catastrophic "system error".To solve the equation, Hannah recruits Sebastian: a wealthy, "monastic-chic" intellectual who can find a soul in a pivot table but is routinely defeated by the instructions on a box of frozen pizza. Together, they must navigate London's industrial shadows to find a subterranean vault hidden ninety degrees off the official floor plan.Up against a criminal empire and a henchman significantly more worried about his anti-hair loss shampoo than a security breach, Hannah is about to discover that the most dangerous variable in a heist is an auditor with a very long memory.
It's time to execute the Cardigan Gambit.
