David Luty died in Leeds in 2008. Unmarried and with no children, he'd worked all his life as an accountant for the Yorkshire Electricity Board. Initially the only record the team at Fraser and Fraser had was name and date of death. By using a mix of experience and inspired hunches, a family tree soon begins to emerge.
