Mwengwe is a friend of Ted Crilly and Dougal McGuire.


When the two priests are at their wits' end following their torture at the hands of Sister Assumpta, who was sent by the Matty Hislop nuns to help solve their problems with keeping their Lenten vows, they decide to flee and Dougal suggests visiting Mwenge as he has satellite TV and his parents are away until Ted points out that he lives in Addis Ababa.
