When a man goes up the Ferris wheel very much alive, but comes down dead, local small-town police suspect a heart attack. But one person is calling it foul play, a Miss Marjorie McClelland, full-time mystery writer/part-time sleuth. In 1935, Depression-era Connecticut, Marjorie's dogged determination and independence is a breath of fresh air to some, and a source of consternation for others. Marjorie's fiancé, an achingly handsome police detective, wishes she'd just stay home and act a little more ladylike. Undeterred, blonde and lovely Marjorie charms her way into what becomes a full-scale murder investigation. But not without the maddening assistance of a bored, yet altruistic, millionaire, Creighton Ashcroft, who, when he's not swapping barbs with Marjorie, tries to impress her by doing a bit of aristocratic snooping on his own.
