Who Is "Bob"?

One thing I tried to do in The Cross Earths Caper was reintroduce a few obscure UK Golden Age characters.

When the Black Tower heroes found themselves in the 1950s of another Earth they ended up on the Moon. Not just that but they found that Selenites had put members of the 1930s Society for the Suppression of Crime (SSC) and released them....only to have them sacrifice themselves (?) to save the Earth from a Planet Killer cannon....it's the way things were rolling.

The mystery of "Bob" continued. The amnesiac power house was introduced and toward the end of the book a BIG clue was given about who he might be.

If I ever manage to get back to publishing new books the secret of "Bob" will need to be cleared up!
