About the book

It was supposed to be the perfect history trip: three days at Hollowmere House in the Yorkshire Dales, with a priest hole, a rooftop observatory and a six-hundred-year-old treasure called the Hollowmere Hours.

Then Storm Ingrid hits. The river bursts its banks, the only bridge vanishes under the flood, and in the morning the owner of the house is found dead in the library, with the door locked from the inside.

With the police two days away and a houseful of suspects, Maya and her friends must work out who had a reason to want Julian Thorne dead, before the water goes down.
