Martin "Henry" Dawson, a dying doctor.
A lapsed Scottish Presbyterian, but of the old school, the kind not easily stopped, not when they believed they were duty-bound to do what was right.
A lapsed Calvinist on a catholic mission.
For Dawson's goal was "Penicillin-for-all".
Particularly at the height of a Total War in which - if you believed the newspapers - his Allied nation opposed the Nazis mostly for their nasty habit of mentally dividing the world in the deserving elect and the non-deserving non-elect.
Of course, in fact, much of the Allied world mentally did the same - and publicly opposing Dawson's goal merely exposed this awkward fact.
Poor Frank and Winnie when they took on Henry : they simply never stood a chance....
