What to Do When Someone Dies - Nicci French

'This is not my world. Something is wrong, askew. It is a Monday evening in October. I am Ellie Falkner, 34 years old and married to Greg Manning. Although two police officers have just come to my door and told me he is dead, I know that can't be true because that happens in a world meant for other people...'

When Greg Manning died in a horrific car accident he was not alone - beside him in death was a mysterious woman called Milena Livingstone. For Greg's widow Ellie it's a double blow, because no one can explain who this woman was or what she was doing in his car. The implications, however, are obvious...

With the image of her perfect marriage in tatters, Ellie decides to find out exactly what was going on. Because somehow the circumstances of the deaths just don't add up.

And to prove it she's prepared to do anything - even if it means secretly infiltrating Milena's life.
