For eighteen year old Lena O'Sullivan, life is predictable and dull. A future of hard work, marriage to a local boy, and a family of her own one day is all she has to look forward to. People from her background know not to expect too much, but Lena yearns for something different. Malachy Berger was different, for him, the world is at his feet. An only child of a wealthy, if peculiar father, a large inheritance, a beautiful house and a fine education are his due. Nobody is in favour of Lena and Malachy’s friendship, but why not? What harm are they doing? Why is everyone so dead set against it?

Life is calm and fairly predictable. Until something unthinkable happens in our sleepy backwater. A crime, but not like anything I've ever seen before. It's a complete mystery. And it's up to me to solve it.
