After eighteen years inside, Johnny Frank is coming out of jail with just one thing on his mind, to kill the man who put him there. But his plans soon go dramatically awry. As his past returns to haunt him, a vicious murder and kidnap force him back on the streets of London. He could choose simply to disappear - if it weren't for Simone.

Through her marriage to Reggie Kray, the author has a unique insight into the inner conflicts of a long-term prisoner, and just as Roberta's life was irrevocably changed by meeting Reg, so Simone's will never be the same again after she enters Johnny's dangerous and unpredictable universe.
