Wherewolf [EPUB ebook] 

Half-vampire Ollie inherits his uncle’s detective agency in the undead town of Skullenia.
With the agency comes his uncle’s staff: a zombie who can barely hold himself together, a zombie the size of a phonebox and with a single digit IQ, a mad professor, and Ronnie – who has the ability to make himself invisible.
Skullenia seems to be the last place that would need a detective agency. At least that is what Ollie thinks, until Count Jocular commissions him to help resolve a series of unexplained disappearances.
But has Ollie bitten off more than he can chew? With the help of his motley crew and some quite frankly ridiculous characters, he attempts to solve this perplexing mystery.
