I recently bought a box of pulp SF from eBay - most dating from the 50s and 60s. Lantern-jawed, pipe-smoking men save the world while their gorgeous female assistants are prone to outbursts of come-hither hero worshiping and swooning - especially when kissed fiercely and unexpectedly by the lantern-jawed men. The latest one was about a worldwide plague where the lantern-jawed hero is a journalist trying to uncover governmental secrecy while trying to decide whether to go to his mistress - young, beautiful, free loving and rich - or whether to return to his ex-wife - a dour and buttoned-up biologist - who has an in on a secret survival bunker. (He's a selfish and cold-hearted bastard, so my bet is on him going with the ex-wife and claiming to have loved only her all along.) “The Collapsing Empire” belongs to this book category.
