Chief Superintendent Strange also shows a clear respect for and of Sergeant Lewis, Morse's loyal assistant, sometimes consulting him directly, and occasionally even (as in "Dead on Time") approving his ideas without reference to Morse. Ultimately Strange gives Lewis strong encouragement to seek promotion to Detective Inspector, as indeed he had encouraged him earlier in the series to apply for a vacant Inspector's position in the Oxford traffic police. However, the character does not appear in the sequel series "Lewis", in the timeline of which, he appears to have retired.
