The Fellowship of the Frog is a typical, fast-paced Edgar Wallace thriller. The plot centers around the identity of an arch-criminal who is using down and outs to do his dirty work.
He murders, he robs, he blackmails... Richard Gordon, a prosecutor, and Sgt.
But it seems that the Frog has some insiders at Scotland Yard, who help captured criminals escape and who help misdirect the forces of justice.
