Wynton Allen was presumably a victim of Alexander Macauley, also known as Zander. Upon investigating files left on records made by the dockmaster of Royal Bay Yacht Club on Macauley's activities on the marina, Dexter discovered a file that read as follows:
On February 14, the board was delighted to announce that Wynton Allen would be moving out of the
den of iniquity that is Miami and onto Zander's ranch to be rehabilitated by honest labor.
Dexter found out that various subject followed the same pattern, they were taken by Zander into rehabilitation on his ranch and were never heard of again.
