The Summer of Dead Toys, by Antonio Hill

I chose this because it was set in Barcelona, and I wanted to learn something about the city.  I learned that tourists are an annoyance to residents.  Hector Salazar, a police detective from Argentina, is returning to the job after a forced probation.  He is teamed with the young investigator, Leire Castro, and assigned to a non-case.  The well-connected mother of a dead student wants further investigation into her son's death, which police are convinced was either accident or suicide.  Meanwhile, his boss puts her career on the line to save Hector from further charges against him.  The language is a little stilted, but the plotting was strong. I'm willing to keep an eye on Hector and Leire.
