An actress killed at her grand piano.

Award-winning actress, Joan Minter, 76, is murdered at a gathering of her closest friends. One moment, she’s making a speech celebrating seventy years in show business. Then the lights go out.

When they come on again, Joan is dead. Blood runs from her head onto the cream carpet.

No one saw the murderer and none of her friends could have done it.

That’s the challenge facing Inspector Angel and his team when they are called out to her luxurious home in South Yorkshire, at the foot of the Pennines.

At the same time, an apparently innocent insurance man is found murdered in his own house. The only clues are a new vacuum cleaner left by the murderer and an open fridge.

What’s the vacuum cleaner got to do with the case? And can Angel hoover up the murderer?

Two baffling crimes. One brilliant detective.
