In 1937 Larry Lambert has a vision of a magnificent pub built on frozen fields 'like a grassy sea'. It is an echo of a single, failed, gay encounter in a fishing boat, and in its construction he invests his energy and his thwarted dreams. He calls it The Dolphin. And so unfolds a moving exploration of the constraining expectations of society on three generations of one family. For Larry, there is the cruel impossibility of being gay in 1930s Britain and his ensuing loveless marriage with the embittered Rosemary. For his daughter, Joanie, there is the crushing weight of duty and respectability during the post-war years. Only granddaughter Lottie pulls free and finds the freedom her grandfather and mother were denied. Larry's decision to build The Dolphin sparks events that play out over decades, tearing one generation apart while bringing another back together.
