Doctor in the House

Brotherly Hate (5x6)

Air date: Oct 20, 1973

Bingham refuses to recommend Paul to Loftus for a senior house post. However when Lionel Bingham, Lawrence's identical but less buttoned-up twin appears, he impersonates his brother and gets Paul the job. Whilst Lawrence launches a bitter diatribe against how Lionel always bested him at everything, a third brother Leonard, turns up.
