JIMMY TASKER WAS an officer who didn't suffer fools gladly. His time in the Metropolitan Police had brought him up against a few already. Now in 1975, he knew that his tour of duty in the anti-terror unit was coming to an end and he expected to be moving on. He didn't expect that move to mean leaving the south of England. Asked to investigate the possibility of a 'mole' in the South Wales Police, he soon wondered if he could uncover the truth - before he made enemies of most of the senior officers he dealt with. Tragedy on a personal level had to be dealt with alongside trying to unravel a far reaching web of deceit and lies which eventually led him back to the higher echelons in the Met.
