SHE WAS THE QUIET ONE

by Michele Campbell, Harper Collins, £7.99, ebook £5.99. Available January 10

CENTRING around orphaned twins and their boarding school master and mistress, this is a tale of unrequited love, affairs and breaking the rules.

The narrative flips between the story and transcripts of police interviews with people involved in events in the run up to the murder.

The narrative powers through to a gripping conclusion, and an unexpected epilogue.
