The Villain's Daughter by Roberta Kray

A gripping, hard-hitting tale of family and criminal ties Sean O'Donnell, small-time villain and family man, walked out of his home 19 years ago and hasn’t been heard from since. Now his daughter, Iris, has returned to the East End in the hope of finding him again. However, she’s not the only one on his trail—the psychotic Street brothers are right on her heels, and they have good reason to want her father dead. With the help of the mysterious Guy Wilder, Iris slowly begins to unearth the horrors of the past, and it isn’t long before she comes to realize that some secrets are best left buried.
