On a foggy night in Hampstead, London, a party has gathered in an artist's studio to weather the wartime blackout. A civil servant and a government scientist match wits in a game of chess while Bruce Manaton paints the portrait. In the kitchen, Rosanne Manaton prepares tea for the charlady of Mr Folliner. When the murder of 'Old Mr. F' is discovered by his Canadian infantryman nephew, it's not long before Inspector Macdonald of Scotland Yard is called to the scene.

London, 1945. The capital is shrouded in the darkness of the blackout, and mystery abounds in the parks after dusk. During a stroll through Regent's Park, Bruce Mallaig witnesses two men acting suspiciously around a footbridge. In a matter of moments, one of them has been murdered; Mallaig's view of the assailant but a brief glimpse of a ghastly face in the glow of a struck match. The murderer's noiseless approach and escape seems to defy all logic, and even the victim's identity is quickly thrown into uncertainty.

The Second World War is drawing to a close. Nicholas Vaughan, released from the army after an accident, takes refuge in Devon renting a thatched cottage in the beautiful countryside at Mallory Fitzjohn. Hard work and rural peace seem to make this a happy bachelor life. On a nearby farm lives the bored, flirtatious June St Cyres, an exile from London while her husband is a Japanese POW. June’s presence attracts fashionable visitors of dubious character and threatens to spoil Vaughan’s prized seclusion. When Little Thatch is destroyed in a blaze, all Vaughan’s work goes up in smoke, and Inspector Macdonald is drafted in to uncover a motive for murder.

Trouble is brewing for the Hoggetts and their friend Chief Inspector Macdonald in Lunesdale, deep in the Lancashire fell country. By the jagged cliffs and chilling depths of a secluded quarry pool, strange noises disturb the night, and after an architect surveying the area is nearly hoisted into the cold waters by an unseen assailant, suspicions of a cold current of crime running through the area become a matter for the police.
