Many "cozy" mystery series are peppered with colorful characters, amusing inside jokes, and interesting locations. Bowen's Evan Evans series certainly fits this bill, but with "Evan Can Wait" the series moves into deeper, more interesting waters.
As usual, this book finds Evan Evans at home in Llanfair, an underappreciated sleuth whose fellow citizens are as colorful--and as hard to get to know--as the mountainous terrain. As usual, outsiders descend upon the town to wreak various sorts of havoc and get one of their number murdered.
But the mystery in "Evan Can Wait" takes a very satisying turn--we learn a great deal about Bronwen, the town schoolteacher who has been such a good-girl cipher up to this point, and we learn more about some of the darker parts of recent Welsh history, such as the life of a typical slate miner. Not only is there a recent murder to solve, but the murder has links to a decades-old crime and the two are tied together in a satisfying fashion at the end.
In short, it is still a light, amusing read, but with a little more depth to make the characters more real, the situations more complex, the ending a little more nuanced.
