Mitch arrives on the small Mediterranean island of Gozo, taking a holiday to escape from domestic and sexual trouble at home. He’s been invited by Bob Southern, a fellow doctor now working at the army garrison at Valetta, who wants to consult Mitch on "a delicate matter." 

Bob is concerned by the apparent suicide of a young lance corporal, Ned Southern, who plunged to his death from Gozo’s cliffs. The authorities said he was being blackmailed, but Ned’s grief-stricken lover Alf insists that he was murdered. Suspecting an official cover-up of a queer scandal, Mitch gets to work on an investigation that leads him into a labyrinth of lies, false identities and secret sex.

As another body is washed up on the rocks, a gallery of suspects begins to form. Claire Sutherland, the ageing stage star who knows all the gossip on the island; Henry Jessop, the beautiful youth who may not be as innocent as he looks; Joseph Vella, a ladies’ man with a deadly secret; Major Telford, whose "artistic" photographs of the island men may tell a more sinister story…

With tension, humor and plenty of Mitch Mitchell’s exuberant sexual encounters, The Sun Goes Down cranks up the Mediterranean heat!
