She first appears in "An Inspector Calls" and is played by Iris Sadler.

Profile
Gladys is a shameless gossip, as revealed when she tells Mr. Brown's entire class about his birthday and Miss Courtney about Mr. Brown's "engagement" to Danielle. She used to sing in a choir and was known for being able to dance The Veleta skillfully. She also has a sister who fell in love with her 30-year-old milkman when she was 65.

Gladys tells Mr. Brown a little about her husband Wally in "Take Your Partners", but she later says Mr. English reminds her of her late husband. This makes it unclear if Wally has died or if she's referring to a man she was married to previously.

In Season 4, Gladys is replaced by Rita.
