"Saint John's Ambulatory"

Saint John's Ambulatory is a murder mystery, but there are aliens in every shadow. Only one man has evidence of extraterrestrials on Earth, but now, he's dead. The Aleronde Trilogy is three very different books but one epic sci-fi tale. Visitors from Earth witness the shocking downfall of Aleronde. They share an unexpected role in this catastrophe with a mysterious figure from the past who unpicks the fabric of the Aleronden empire with that most dangerous thing: an idea. The Problem with Uncle Teddy's Memoir and Saint John's Ambulatory are each prequels to Aleronde the Great and can be read in either order.
