Disappearing off the face of the earth by David Cohen

Transit Lounge, 2017. ISBN 9780995359482
(Age: 15+) This contemporary story is set in a self storage business in Brisbane. Narrated in the first person by the owner Ken, it details the decline of the business where defaulters of the storage units disappear and Ken is able to sell the contents to recoup rental costs.
Bruce, his employee, appears to be mixed up in the disappearance and 'messing' with Ken's mind and view of what is happening.
Along with the decline of the business is the mental decline of both men.
While the story is engaging and I read it in one sitting to see what happens at the end, the ending is disappointing and somewhat inexplicable.
There are a few sub-plots that confuse the main story.
