After Doctor Who
After Davison left Doctor Who in 1984, he did not work on another popular series until 1986, when he played Dr Stephen Daker, the ingenuous hero of A Very Peculiar Practice, written by Andrew Davies. The surreal comedy-drama was revived several years later as A Very Polish Practice. Davison also played the lead in Campion, a series based on the period whodunnits of Margery Allingham. This, and the opportunity to play Tristan Farnon again in 1985 and 1990, kept Davison busy until the early 1990s, when he gradually faded from the public eye. He continued to appear occasionally on television, including playing the leads in Fiddlers Three (1991) and Harnessing Peacocks (1992) and an appearance on the American show Magnum, P.I. (in the feature-length 1985 episode "Deja Vu", set in the UK). In 1994–1995, he co-starred in the British sitcom Ain't Misbehavin', then in 1995 he presented "Heavenly Bodies" a six-part series about astronomy, broadcast on BBC1. This led to him being featured on the cover of "Practical Astronomy" magazine (Volume 1, number 5, dated March 1995). It was not until 2000 that he returned in another major role, that of David Braithwaite in At Home with the Braithwaites.
