The Feathery plot centers around a unique type of golf ball used during a record match at St. Andrews, Scotland in 1849. The story is set in San Diego, London and New York, as well as in ancient and modern Scotland. The game of golf blends with mystery and suspense surrounding an obsession so strong by some to own this valuable antique feathery golf ball that they'll commit murder to satisfy it. A sub-plot involves an attempt by a gambling interest to fix the British Open when the leading player's caddie is abducted to force his withdrawal.
