Honeymoon with [love] murder

The murder of sleazy/disreputable Jesse Penrick interrupts Annie and Max Darling's honeymoon when Annie's friend, desperate for assistance, phones her. The friend's subsequent disappearance galvanizes the island of Broward's Rock (off the Carolinas), precipitates the involvement of a gaggle of sleuths, and provides for the author's frequent allusions to various mysteries (Annie runs the Death on Demand mystery bookstore). The literary references fall a bit thick, as do appendant crimes, batty characters, cliches, and extended "important" messages. True mystery devotees should love this.
