This is an elaborately choreographed crime against unsympathetic wealth and venal greed. To these powerful reader (and potentially viewer) inducements, a third has been added via a quixotic revenge motive. Debt and disorderly conduct are about to expel drunken Alex Sheldon from the moorings outside a Spanish yacht basin where he lives aboard the old MTB he had commanded heroically for the Royal Navy in World War II. Before he purchased it, the MTB had been named for the Lewis Carroll poem, Jabber-wocky, which warns against the ""frumious bandersnatch."" Sheldon snaps his cap and goes completely frumious when a fantastically wealthy Greek buys the siding to develop as a private marina and expedites Sheldon's removal after his particularly stupid drunken orgy. It makes a certain sort of sodden sense to ex-war hero Sheldon to revenge himself against the Greek tycoon who had collected his original bundle as a war profiteer. Sheldon recruits some mentally/morally wounded members of his wartime command, sobers them up and prepares them for ""Operation Bandersnatch""--the kidnapping of everybody aboard the Greek's floating palace with a ransom set at two million pounds. All craftily planned, skillfully executed, adroitly balked.
