A body washes up on a beach on a Greek island. Two women at a retreat on the island discover the body early one morning before their yoga session. They are both required to give witness statements to the police but both women are hiding something.
DS Abby Foulkes is back in Greece to investigate the murder of a friend in the late 1990s. She was invited back by Lieutenant Angelo Christofis whom she met whilst holidaying on Skiathos in 2014. But he's recently had a baby and she senses there's something wrong. She hasn't been able to get in touch with him and finds herself all alone in Greece, on another island following up a lead, outside his jurisdiction. Cast adrift, she must keep all her wits about her while she investigates old and new crimes at the same time.
