Interestingly, all three of these are ON SALE at 50% off at Audible.com (membership required), but also all three audio books are available for even less as WhisperSync versions. I don't have an opinion about the other two for Audible versions, but for
Midnight Riot/Rivers of London, the Audible version is superb and highly recommended.

"I LOVE this Book!"
For several years now, I have studiously avoided any and all of the current books involving vampires, ghosts, werewolves, spirits and similar creatures in mystery and other genres. I didn't read horror stories, period.
Then I read some member reviews of "Midnight Riot," and thought I'd give it a try, despite the dead, undead and non-human monsters. What a revelation! This book gives the reader a rollicking ride through modern day London in the course of a murder investigation. It is fast-paced, engrossing and hilarious. I laughed out loud repeatedly when listening. In addition, I learned a bit of history about various sites in and around London.
Constable Peter Grant, having just finished his probationary period with the Metropolitan Police, interviews a witness to murder, only to find out that his witness is the ghost of a man who died 120 years before. As a result of his being able to see and converse with the ghost, he is recruited by Inspector Thomas Nightingale to work in a unit (made up of only Nightingale and Peter) whose "beat" is anything non-human, undead or uncanny. Turns out Nightingale is a wizard, and Peter becomes his apprentice. Now, sweep all ideas of Harry Potter out of your mind -- this is not a Hogwarts type of story.
As Peter, Nightingale and Constable Lesley May, a friend of Peter's, work their way through the mystery. they encounter a great deal of violence, a number of River Spirits, ghosts, vampires, and general confusion. Peter Grant is a lovely character, who is smarter than he realizes, and who looks at London and its residents with a jaundiced eye and very ironic comment.
Other reviews give a much more detailed description of the book, and I refer you to those other descriptions. I want to talk about the narrator, Kobna Holdbrook-Smith. He is perfect! He gives Peter's character just the right accent and attitude, that of a young mixed race man from a working class background who has a breezy attitude and many a smart remark to make. Then he makes Nightingale a well educated gentleman of at least a century earlier. Male and female voices, London accents, German, Indian, Middle Eastern, African, Caribbean and Japanese voices are all wonderful. KHS brings the book to life beautifully.
HIGHLY RECOMMENDED!
I couldn't have said it better.
