Rescued slightly by a few delightful character performances, Doctor Eduardo is a so-so rendition of an Arthur Conan Doyle story in which a stranger from South America meets sleepy small town America.  There he finds success in his practice along with friendship and true love, though fear and bigotry also.  Pilfering an all too familiar narrative device from many an opera (I won't spoil it) Keane's story resolves itself too tidily and with much less of a dramatic turn than listeners would hope.  Robert Dryden rescues the play with some over-the-top but enjoyable performances including as town mayor and as the coroner.  Keane's radio play would have been better if development of the title character had been on par with those of the mayor and his son and daughter.  Mystery Theater seems to have greater success with renditions of other authors' works such as Poe (when compared to Doyle).  For great dramatic remakes of a literary giant, check out 'Fall of the House of Usher' and 'Cask of Amontillado,' and leave 'The Red-headed League' alone.  I give 'Doctor Eduardo' 2 out of 5 stars. - JUROR # 4
