Every family has its quirks. Some families chew too loudly; others argue about politics at Thanksgiving. My husband’s family, however, had a much more expensive flaw: they were professional freeloaders.

Arthur and Eleanor Vance, along with their spoiled daughter Madison, were masters of what I like to call the “Ghost Check.” They possessed a refined palate for the finer things in life—five-star restaurants, private wine reserves, imported truffles—but an astonishing inability to physically touch a leather billfold when it arrived at the table.

For years, nobody confronted them. They were wealthy on paper, dripping in designer clothes and leasing luxury cars, but they were notoriously, aggressively cheap.
