This thriller is one of the best books we've read

The Secret Room by Jane Casey became an instant hit when it was published earlier this year, with the author becoming an Irish Times #1 bestseller.

Casey is undoubtedly one of the best crime authors in Ireland, so having a new book of hers to delve into is a real treat.

The Secret Room has been hailed as one of her best novels yet, with readers raving about it.

One said, "Should come with a warning - it is seriously addictive."

Another wrote, "I finished it yesterday and have had to reread the last chapter again today just because."

What is The Secret Room about?

'A closed door.

An impossible murder.

At first glance it looks like an accident. No one went in with her. No one came out. But all the signs point to murder.

For DS Maeve Kerrigan, the case is a welcome distraction. But when shock news hits close to home, affecting her partner, DI Josh Derwent, she faces the toughest challenge of her career. And if she fails her world will never be the same again…'
