With Anna's signature perfume still hanging in the air, a painting falling from the wall of its own accord and a horse fatally kicking out after being spooked, Reggie's fears seem to have some foundation, although Kitty is quick to point out their coincidental nature.

And when Sidney arrives at the station he finds his friend with his knuckles bruised, and Eddie, dead on a stretcher.When DCI Benson questions Geordie's innocence, Sidney leaps to his friend's defence.

At the vicarage, Leonard and Mrs Maguire are at each other's throats as an ill judged remark about Mrs Maguire's love life, and the accidental loss of some sentimental postcards leaves both feeling raw and misunderstood.As Gary Bell waits to discover his fate, Sidney seeks to avoid a further injustice taking place. But as he digs deeper he finds himself questioning precisely whether he really knows Geordie as well as he thought. Could Geordie have beaten Eddie to death? Will Sidney keep the faith in his friend? And will Gary avoid the hangman's noose?
