It's a pretty typical beginning chapter series - some nondescript kids, simple mysteries, and a quirk that defines the series. The quirk for this series is that all the mysteries are set in famous ballparks. Cousins Mike and Kate are the detectives and Kate's mom is a sports reporter, which provides the backstory for them having access to so many famous ballparks. In this particular mystery, someone is cutting the historic ivy in Wrigley Field and the kids have to decide who's a suspect, look for clues, and set a trap to catch the culprit.
Along the way, there's lots of history about the ballpark and the teams who have played there as well as the fans. The "Dugout Notes" at the back add even more details and context for the various events and traditions referenced in the book.
Verdict: This is a nice idea - mysteries with a baseball theme - and while there's nothing outstanding about it, it's a perfectly serviceable series. It's a nice touch to make the mom a sports reporter; I have a lot of girls ask for sports books and this does a good job of having a female detective and showing a nice balance of male and female fans. If you have space for another beginning chapter mystery series, this is a good choice.
