The line

Unlock the door to the criminal mind in The Line, the outstanding debut from Ireland's leading criminal psychologist.

Here Dr Ian Gargan unravels the motives of some of the nation's most violent and prodigious offenders, mapping the fine line between right and wrong - the set of life circumstances that could make any of us cross the line into criminality and violence, highlighting that there aren't many differences between us and them.
