At the conclusion of The Return of Clubfoot, Dr. Grundt has been left for dead on a south sea island by former secret agent Desmond Oakwood. Oakwood and his brother Francis are now retired from the Secret Service and are living comfortably retired in England. But the body of an apparent suicide is discovered in a car park in London, and the possibility that Grundt is alive and seeking revenge in England pulls the Oakwoods out of retirement to once again face the sinister and deadly CLUBFOOT. - Summary by sjmarky
