Murder Down Under - Darcy Sweet Mystery, #17

Darcy and Jon are finally married and heading to Australia for their honeymoon. A whole week in Tasmania staying at the Pine Lake Inn with nothing to do but act like tourists. No ghosts to deal with. No mysteries to solve. Just rest and relaxation. It will be a welcome change having nothing to worry about. That is until they actually arrive at their destination. They find that three people have died just recently under suspicious circumstances and a fourth has just been released from hospital.
That is definitely something to worry about. The local police department doesn't seem too worried about it though so it's up to Darcy and Jon to figure it all out. Will they be able to catch a killer in their midst before the unknown person strikes again?
