Murder on the Rocks by T.E. Kinsey
I have to say I enjoyed Murder on the Rocks tons more than the other one in this series I've read. Lady Hardcastle and Florence are at a friend's island fort in Devonshire. JB McIntyre has recently converted the building into a hotel and has invited a group of people a kind of a pre-opening weekend. Of course, it turns into a less than relaxing weekend. First, some jewelry goes missing, then a guest is murdered with a narwhal tusk, and finally a storm rolls in, effectively cutting them off from the mainland.
Lady Hardcastle and Flo are joined by an interesting group of JB's business associates and friends, all of whom are now suspects. Each of them, of course, has a secret that may or may not be known by the others and a reason for wanting the dead man gone. And they all seem to have alibis, no matter how often Emily and Flo review the timeline....
