Can stopping time solve a murder . . .?  A delicious mystery adventure for fans of Robin Stevens and Cressida Cowell from the award-winning author Michelle Harrison, author of the Pinch of Magic series.

When the Morrow twins, Merry and Spike, arrive at dusty old Fox House, they think spending their holidays there is going to be dull. But they soon discover that there are secrets to the old house. A missing woman, a baby left on the doorstep, a locked study. As the mysteries pile up, the girls begin to investigate. The twins also have a secret of their own: they can stop time.

What happened in this old house? And can their strange powers help them solve a decades-old crime?
