A debut from the granddaughter of Kim Philby, Britain’s most famous communist double-agent, The Most Difficult Thing is set between London, the Maldives and the Greek islands and is an irresistible combination of espionage and domestic suspense.

On the surface, Anna Witherall personifies everything the aspirational magazine she works for represents. Married to her university boyfriend David, she has a beautiful home and gorgeous three-year-old twin daughters. But, beneath the veneer of success and happiness, Anna is hiding a dark secret. She finds herself drawn into the dark and highly controlled world of secret intelligence and is forced to question her family’s safety, and her own.
