Westlake Donald E. Bank Shot

When John Dortmunder sets out to rob a bank, he really means it. He steals the whole thing. With the help of his usual crew, as well as a sophomoric ex-FBI man and a militant safecracker, Dortmunder puts a set of wheels under a trailer that just happens to be the temporary site of the Capitalists' & Immigrants' Trust Corp.
When the safe won't open and the cops close in, Dortmunder realizes he's got to find a place — somewhere in suburban Long Island — to hide a bank.
