Delicious over-the-top Wallace craziness. Tommy Cawler actually has some depth and ends up a sympathetic character. Solid Graham Coton art. One odd note: in the final panel Dick's heart-throb Sybil Lansdown has suddenly turned into a twelve-year-old! I can certainly understand Dick's baffled expression.
Another oddity...on a number of pages certain dialogue and captions are typeset rather than hand-lettered like the rest of the story. This sort of thing usually means the story was a cut-and-paste job taken from another source (e.g. a newspaper strip). I thought the Wallace tales in [i]Super Detective Library[/i] were original to the comics. Am I wrong?
