The Phantom (Frew Publications)

Diana's mother is not happy with her daughter’s feelings for The Phantom. In an attempt to make Diana forget Kit, Lilly goes on the hunt for "better" suitors. She believes she has found such a man in Baron Danton. However, when the Baron takes Diana on a visit of his yatch and Diana sees something she was not supposed to both her and the Baron disappear.

Now the Phantom must track them down with hardly any clues. This is one adventure that will never be forgotten!

This is actually a “continuation” of the story The Game of Alvar. For some reason this edition begins about halfway through the tale, with the first half of the story recapped on the first page.
