A Sociopath’s Guide to a Successful Marriage by M. K. Oliver

The witty and gripping new thriller introducing your new favourite murderous heroine: Lalla Rook.

There’s a dead body in my living room.

I’ve not called the police because it was I who stabbed him. Seven times in all. The truth is, it’s surprisingly difficult to dispatch someone with a vegetable knife.

In case you’re wondering, the dead man is not my husband. I do resent our pitiful sex life and his woeful lack of ambition, but I wouldn’t murder him for it. Not yet, anyway.

Right now, I have far more pressing concerns: scheming to get my daughter into the perfect school; buying my dream home in Hampstead; and disposing of a corpse.

A woman’s work is never done. I’ve created the perfect life – and I’ll kill to keep it.
