This is a pretty bad episode. LeStrade has drawn a blank as he attempts to solve a series of heists of major British treasures. These things have been disappearing and no one can seem to figure out who is doing them. Based on a flimsy observation, Watson gets it in his head that Holmes is behind the robberies. He throws away years of friendship and even enlists LeStrade's help in pursuing his best friend, thinking he has gone around the bend and needs to be put in a home in the country. Of course, not all is as it seems and the two make absolute fools of themselves. Even for this lightweight television series of the fifties it leaves a lot to be desired. Such a conclusion would certainly have compromised a great friendship.
