The book begins with a boy at military school being kidnapped while on a
cross country run. The kidnappers take him to a remote cottage and send
ransom notes to the boy's father. The boy tries to escape by climbing up
the chimney but fails. His roommate at school is somewhat hapless & bad at
running but helps solves the mystery.
Front cover was blue and had a jeep/land rover on it.
I read it in the mid-1990s but imagine it was published maybe 20 years
before than that? I THINK it was set in Britain but could well have been
east coast of USA.
