The King's Treasure, The Falcon #4, by Mark Ramsay; Signet/The New American Library, copyright 1982, 1983; March, 1983.
After reading the first three Falcon <link://slug/2006-04-04> books, I did some looking on-line and found the fourth book. It turns out that Mark Ramsay is a pen name for John Maddox Roberts. This volume of the series contains the first chapter of Falcon #5, Greek Fire, but I haven't been able to find any proof that #5 was actually printed.
