Somehow she'd always known that she would end like this. In a small square room, in a small square flat. In a small square box, perhaps. Cardboard, with a sticker on the outside. And a name...

An old lady dies alone and unheeded in a cold Edinburgh flat, on a snowy Christmas night. A faded emerald dress hangs in her wardrobe; a spilt glass of whisky pools on the carpet. A few days later a middle-aged woman arrives back to the city of her birth, her future uncertain, her past in tatters. But what Margaret Penny cannot yet know is that in investigating the death of one friendless old lady, her own life will become enriched beyond measure.

The Other Mrs Walker - a detective story with no detective - is a beautiful, beguiling and intensely moving debut.
