Santa Cruise

Alvirah Meehan, the lottery winner turned amateur sleuth, and her
husband Willy, private detective Regan Reilly, her new husband Jack, and
Regan's parents are all guests on the Royal Mermaid's maiden voyage,
the Santa Cruise. The ship's passengers include members of the Oklahoma
Readers and Writers group - who are planning a mystery seminar dedicated
to a Ghost of Honour, the late Left Hook Louie - as well as assorted
other charitable folk all planning on a restful post-Christmas vacation.
What the guests don't know is that two escaping criminals have been
smuggled on board. The hoped-for tranquility quickly vanishes when a
terrified mystery fan swears she has spotted the Ghost of Honour in the
ship's chapel, and soon after - while a storm develops outside - an
attempt is made on the life of a feeble passenger. As the Royal Mermaid
sails on through troubled waters, Alvirah, Regan and Jack are uncovering
clues that lead them to dangerous criminals.
