Death Takes a Hike - The Jen Madden Mysteries, #3

Foxy, bisexual, not-so-closet lesbian and ad woman, Jen Madden, moonlights as an amateur sleuth solving sex related murder cases. Her latest account is a Funeral Home franchise run by the mega-rich Sheehan Brothers. At the dynasty's beach-house party she finds one of the brothers chopped into sections. When the other brother's wife is pushed over a cliff, her daughter engages Jen to discover who is attacking the dynasty and why.
In between hiking the Great Ocean Walk for a local tourist organisation, Jen unearths the funeral dynasty's multiple family skeletons. Then the second Sheehan, his mistress and younger son are shot. The police see it as a murder/suicide but Jen sees much more and, by committing her foxy body to various erotic perversions, uncovers blackmail, deception, perversion, lesbianism, necrophilia and greed.
Then the oldest son's wife disappears. Next, the son is shot dead. Although Jen unearths one killer, she misses the ultimate villain - an almost fatal error. It's another tight, ingenious plot from the mistress of erotic chicklit crime.
