Andy McNab's Bravo Two Zero casts a long literary shadow. Arguments about differing sides of the same story and apportioning blame aside, it set a standard and whetted the appetite for explosive stories of military endurance and bravery. Little has changed in 20 years; something inevitably goes wrong (in Army-speak "no plan survives contact"), survivors must fight their way home, relationships are strained, we should expect the unexpected, someone won't make it but British pluck will win out etc. It is to Bishop's credit that he makes the formula work in Follow Me Home, but with no "true story" tag to support it, the characterisation sometimes feels thin.
