About “The Final Case,” Doctor Scofield, Captain Underhill’s personal physician, comments, “A most interesting case study. It is both sad and ironic that the mental affliction Captain Underhill used to pretend to suffer from: that of being senile, was ultimately the very thing that laid him low. And yet, in the annals of crime solving, if this final case does nothing else, it proves the kind of natural-born sleuth my good friend, Waverly, was.”
