A new children’s book, “Sam Saddlebags, Horse Detective: The Case of Horseshoe Cove,” has been released by a Springfield author. The book is the second in a series by Irene Martinko, a junior at West Springfield High School.

The story involves a horse who solves mysteries, and is aimed at 7 to 9-year-old readers.

The illustrator, Noah Farlee, an art student in college in Vermont, based each illustration on a classic movie poster. The first book in the series, “Sam Saddlebags, Horse Detective: Movie Madness,” was written when Martinko was in middle school and Farlee in high school.

Both books are available on Amazon.com.
