The title phase, "A Tan and Sandy Silence" is not mentioned verbatim in the book. However, the title is referenced on Page 191 of the first edition, "...a message without sound. A sandy, tan farewell."
McGee's sidekick, Meyer, plays a frequent, but small part in this book as McGee assumes a different identity, "Gavin Lee" while spending most of the book away from his normal home in Slip F-18 at Bahia Mar Yacht Basin in Fort Lauderdale, Florida in favor of the hot April climate of the island nation of Grenada near Grand Anse Beach.
