In Holloway two brothers, Ritchie and Michael Spires are aspiring gangsters. Michael is kind and placid but Ritchie is nasty, self-centred and the driving force behind the brother's future success. In Barnet, best friends Sue Nelson and Ellie Evans are young, free, single and out for a good time. Ellie, like Michael, is sweet and kind whereas Sue is the mirror image of Ritchie but when the four meet it isn't a case of opposites attract. Within a year and after a pregnancy and a forced marriage, something dark and horrific happens to one of the women. Something so awful that it's kept buried deep inside, kept a secret between just two people for over twenty years. When the truth can no longer be hidden and is forced to surface, will it blast all of their lives apart or will they be able to forgive? On the tail of one brother and desperate for revenge, Scottish gangster Tommy Makenzie is out for blood. Having waited over twenty years to administer revenge for an injustice carried out against him and his brothers, will he succeed or can his target escape him. Forbidden fruit is a harrowing tale of love, betrayal, vengeance and the ultimate taboo.
