No depth and too long between publications
Reviewed in the United States on October 31, 2019
First I will offer that the two authors have much success in their individual publications. Although the story at the foundation of the four novellas is interesting, the presentation in short novellas was not cohesive or enjoyable. Parts 1 and 2 of this story were published over a year ago. It is a long time to wait for parts 3 and 4. It was difficult to remember the clues from the earlier books. Moreover, the tangential murders in each novella were rushed and in two instances, distracting.
The story, in its entirety could have been published in one book and at a fraction of the cost (the sum of the four novellas exceeded most books). I am not a fan of using novellas to build a story.
