Discover the exquisitely told tragic tale of thwarted love behind the major new film adaptation

It is in 1950s' Brighton that Marion first catches sight of the handsome and enigmatic Tom.

He teaches her to swim in the shadow of the pier and Marion is smitten - determined her love will be enough for them both.

A few years later in the Brighton Museum, Patrick meets Tom. Patrick is immediately besotted and opens his eyes to a glamorous, sophisticated new world.

Tom is their policeman, and in this age it is safer for him to marry Marion. The two lovers must share him, until one of them breaks and three lives are destroyed.

Amazon released the latest trailer last week starring Harry Styles, Emma Corrin and David Dawson, based on Bethan Roberts’ exquisitely told tragic tale of thwarted love.
