Post-WW1 British ace, Neil Mallory, is acting as flying courier in the Brazilian jungle. Well, OVER it, until a plane crashlands and he teams up with a dubious character, Captain Sam Hannah.
Together they work the dangerous territory and run into a mountain of problems with nuns, loose and better women, dangerous flying, murder and eventually a slaughter.
They compete against each other until…well, you’ll just have to read it.
Originally published in 1971, released again in 1997 and again in 2010, this enduring fast story provided me with several good bedtime reads.
