The Mystery of Mercy Close, By Marian Keyes

We first met the dysfunctional Walsh family in Keyes's zingy 1995 debut novel Watermelon.

Four of the five sisters have now appeared in their own novels, and Keyes's fan base will be delighted to catch up with the youngest, Helen.

Now in her thirties, this whip-smart misfit has become a Dublin private investigator. As she snoops for clues in her latest case she entertains with her easy chat, humorous insights and updates to her Shovel List: "all the people and things I hate so much... I want to hit them in a face with a shovel."

Keyes's long reign as The Queen of Chick Lit continues.
