Hebe was Lady Barbara Wellesley's personal servant. She accompanied Lady Barbara aboard the HMS Lydia, where she was either kept locked in Lady Barbara's cabin (where she slept on the floor), or under the eye of her mistress. Hebe was rather mischievous. Lady Barbara described her as drawn to men as a moth to flame. During her time in the tropics, Hebe always wore a bright red handkerchief.

After her mistress married Horatio Hornblower, Hebe continued to serve her at Smallbridge. Hornblower carried some animosity for Hebe, and never quite grew adjusted to her.

In Captain Horatio Hornblower R.N., Hebe is portrayed as a Hispanic woman (instead of a Black one) by German actress Ingeborg von Kusserow.
