My Father's Friend — David Walker

In that unforgetable 1940 summer known as the Battle of Britain, the date September 15th stands out as the day the tide of war turned. Two massive waves of German bombers and their fighter support set upon the defences of London. They were met with the complete, unleashed commitment of Fighter Command. This gamble, against all the odds, achieved a stunning defeat against the might of the Luftwaffe. But if the 2nd attack wave had come earlier, even just a half an hour soone, the RAF's entire fighter defence might have been caught refuelling and arming down on the ground. What if more than mere chance was involved in that delay? This novel is about that one, silent hour which may have been purchased at an unknown cost.
