Involved by Accident is a fast-moving drama covering just ninety-six hours in the life of Stephen Leigh-Grace as he tries to put his life back together following the death of his wife. While moving his boat from its winter moorings to a coastal marina ready for his family's summer cruising season, he accidentally becomes involved in an interracial attack. Initially thought to be involved by the police, he is arrested but later released, only to be savagely attacked upon returning to his boat. A number of relationships begin to develop, and the pace of the story is maintained as the police attempt to discover if the two assaults are connected.
