Alchemist Enigma (Vampire Dead-tective #5‪)‬

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

Liz and Vince must solve the mystery of Tim's death, and the race is on between them and Ruthven as they try to save the city and the paranormal world from his ruthless power. To do that, they enlist the help of their friends in the supernatural world, but in a game of hide-and-seek they find themselves running into more trouble than they planned.

Fates intertwine and confrontations are made as the pair of dead-tectives find the clues and solve their greatest case, or die trying. This time permanently.
