Marianne's Memory is the third novel in Winona Kent's accidental time travel / historical romance series, featuring Charlie Duran and her 19th century companion Shaun Deeley.

A Beatles badge from 1965 accidentally sends Charlie and Shaun back to London at the height of the Swinging Sixties, where they're mistaken for KGB spies and subjected to a terrifying interrogation.

Rescued by top-ranking MI5 agent Tony Quinn, they soon uncover the details of a child born out of wedlock to Charlie's mum and the uncomfortable truth about Charlie's dad's planned marriage to selfish socialite Arabella Jessop.

Further complicating their journey into the past is Magnus Swales, an 18th century highwayman turned time-travelling assassin, and the timely arrival of William Deeley, Shaun's father, who's been persuaded to leap forward from 1790 in order to save Tony from Swales's deadly mission.
