The Cobalt Sky is book 10 in Keith Dixon’s Sam Dyke Investigations series.
The story is driven by the theft of an artwork and the dysfunctional relationships of the artist’s family. The more Sam looks into the people associated with the artist, the more dysfunctional the family appears, and the less likable the artist becomes as a person.
The investigation is hampered by a lack of honesty in several key players, one of whom is the thief. No surprise there, but there are a few surprises in the telling of this tale. A good read.
