The Kilbrannan Sound

After an eerie attempted burglary at his home, ailing millionaire Sir Alec MacFarren is taking refuge on a yacht four miles off the French riviera. Inviting detective Calico Banner to protect him, only his closest friends and family are aboard. But it isn't long before an intruder strikes again, and no one knows for sure what they want or who's behind the attempts to gain access. And as Calico must try to get to the bottom of the mystery, someone on board finds it useful to turn the group's suspicions onto her...

After 'Threes', 'On the Kilbrannan Sound' is the second Calico Banner story.
