The Locked Room - Elly Griffiths

Ruth and Nelson are on the hunt for a murderer when Covid-19 rears its ugly head. But can they find the killer despite lockdown?

Ruth is in London clearing out her mother’s belongings when she makes a surprising discovery: a photograph of her Norfolk cottage taken before Ruth lived there. The only clue is written on the back of the photo: Dawn, 1963.

Ruth returns to Norfolk determined to solve the mystery. Then.

Covid-19 strikes, and Ruth and her daughter Kate are locked down in their cottage. Luckily, the house next door is rented by a woman called Zoe and they become friendly while standing on their doorsteps clapping for carers.

Nelson is on his own because his wife and son are isolating with her mum. He finds himself drawn to Ruth’s cottage where he sees her chatting to Zoe. Something about Ruth’s new neighbour makes him feel uneasy. But before he can investigate further, events take a deadly turn.
