How to rescue a dedicated young nun who's being held prisoner by her anti-Catholic tycoon-father on the top floor of a high-security tower in mid-town Manhattan? That's the latest challenge for the often-hapless Dortmunder Gang (The Hot Rock, Bank Shot, etc.)--when Dortmunder finds himself owing a big favor to the Convent of St. Filumena in Tribeca. The basic plan: Dortmunder and his band of flaky/scary accomplices will hole up in one of the building's offices (where they've found a sexy, mercenary ally) before the place shuts down for the weekend; then, while the accomplices commit assorted robberies throughout the building, Dortmunder will sneak up to the tower--where Sister Mary Grace, a savvy sort of hostage, will be waiting. The basic, unforeseen twist: that evil tycoon just happens to be training a private army of hard-bitten mercenaries to go down and topple an unfriendly South American government! And the mission's big training session is going on this very weekend--up in that tower! So Dortmunder finds himself trying to blend in with a roomful of arms-crazed macho men (the novel's funniest sequence) and winds up having to hide inside a dishwasher--before things start looking up again. . .thanks in part to last-minute help from all those Tribeca nuns. Reliable, if only occasionally inspired, farce from the master of the heist-with-laughs genre--full of endearingly weird characters (including one ancient lecher of a safe-cracker), wry one-liners, and very-nearly-believable escape tactics.
