By Gavin de Becker - The Gift of Fear: Survival Signals That Protect Us from Violence (New edition)

This is an excellent read but better in sections over time or can be overwhelming.

Arrived next day via PrimeGood read. Nice mix of stories / anecdotes and theory. Slightly repetitive in places but certainly gets you think about trusting your instincts.

great read for paranoid /interested and odd people like me , recommended to us by science of serial killers
