Roger Moore and Patrick Macnee are clearly having a laugh together as Messrs. "Holmes" & "Watson". This time our team of sleuths are in the Big Apple hot on the trail of their nemesis "Prof. Moriarty" (a rather underwhelming John Huston) who has just carried out a fairly spectacular bank robbery. Unlike in virtually every other "Holmes" adventure, here he has himself a lady friend - "Irene Adler" (Charlotte Rampling) and soon she and her young son "Scott" are pawns in this perilous game of cat and mouse. The chemistry between the top two keeps this going well enough, but the story is pretty thin and Huston features only but sparingly as the adventure sort of crawls along. The last ten minutes are pretty lively, though and fans of the characters and of the genre ought to enjoy this colourful, well made and scored drama. Not the best, but still just about worth a watch.
