The Mystery of Mercy Close is the tale of strong and sassy but vulnerable, private detective Helen Walsh who is looking for a missing person - but can she find him before she loses herself?

'I have a habit of taking instant dislikes to people. Simply because it saves time . . .'

Wasp-tongued private investigator Helen Walsh doesn't believe in love, fear, depression or hot drinks. But when a missing persons case takes her into the dark, glamorous world of her dodgy ex, Jay Parker, she is drawn away from Artie Devlin, her distinctly unglamorous detective boyfriend.

Caught between smart, stable Artie and chaotic, up-for-anything Jay - two different, but equally enticing men - and plagued by her own black doubts, Helen finds she's beginning to believe in something.

But is it fear, or is it love?
