The Avengers: What the Butler Saw

What the Butler Saw (1966)
Starring: Patrick Macnee, Diana Rigg, Thorley Walters, Denis Quilley, Ewan Hooper, and Kynaston Reeves
Director: Bill Bain
Rating: Seven of Ten Stars

In an effort to find and eliminate the person responsible for leaking government secrets, John Steed (Macnee) enrolls in a school for butlers while Emma Peel (Rigg) sets out to get close to (literally and figuratively) one of the prime suspects--a playboy R.A.F. pilot (Quilley).

The central mystery and threat in this episode is so simple that it's hardly worth of the talents of England's greatest spybreakers--some of the particulars are tricky, but the overall effort would have been very easy to trace to its source once detected--but all the stunts John Steed pulls while trying to ferret out the villains, excellent supporting characters, and a grisly murder and body disposal make this episode a lot of fun.

"What the Butler Saw" is also elevated by a fantastic supporting cast. Thorley Walters (as the stern master of an academy geared toward educating gentlemen's gentlemen; Denis Quilley as the dashing pilot ladies can't get enough of; and Kyanston as the old general who may have crossed the line from eccentric to crazy all play their parts brilliantly. Of course, it helps that they were working with a script that was full of banter and humor. It all added up to  mixture that excused the fact the assignment was almost two simple for our two heavy hitters. (Steed's showing off his disguise skills and his butlering antics are contribute in major ways to this.)

Although, that said, the writers of the episode did make the effort to establish the politically sensitive nature of the investigation, as well as taking a very clever approach to giving Steed a little bit of a personal stake in the case. The writers also did an excellent job with the character of the playboy pilot, making him both a excellent sense of merriment as Emma Peel first pursues him so she can get close to him for the investigation, and then later has to take steps to avoid ending up in bed with him. The ultimate twist to the subplot involving him and Peel catapulted him to the status of my favorite supporting character in all the episodes I've seen of "The Avengers".
