Deadly Wildflowers (Death and Jigsaw #1)

When the sheriff refuses to consider the death anything other than a suicide our sleuthful main character has to investigate and find out if that is true. Trying to follow a missing painting that may be very valuable makes things even more fun to read.
Until the last few chapters, the mystery keeps changing directions. You will never be able to guess the whole story. And there are psychic dogs involved (even if the author will not admit to it).
