"Mother" is a
codename. In the series the incumbent in the role is a
disabled male British government official (played by
Patrick Newell) who uses a wheelchair. He makes his debut in "
The Forget-Me-Knot", which is
Emma Peel's final episode and
Tara King's first. In subsequent episodes he gives orders to
John Steed and Tara King. Prior to Mother's debut appearance, during the Emma Peel era Steed's superior was never identified. However, during the Cathy Gale era, Steed was occasionally seen taking his orders from an individual referred to by the code-name "One-Ten", played by
Douglas Muir in five episodes. This character was succeeded by another superior named "Charles" (played in two episodes by
Paul Whitsun-Jones), then in one episode by
Ronald Radd as "Quilpie". Charles and especially Quilpie were clearly early prototypes for the "Mother" character, sharing several of Mother's mannerisms (though not the wheelchair). Mother appears in most episodes of series six, the last season of the series. He is an irascible yet highly intelligent character, and is a great admirer of Steed and especially his wine cellar. He has two elderly aunts whom, in the episode "Homicide and Old Lace", he entertains with stories of his department's cases. Patrick Newell had played various characters in previous episodes of
The Avengers, most recently Sir George Collins, a sometime
Minister of the Crown and close relative of the
Attorney General, in season five's "Something Nasty in the Nursery". == Bases and locations ==
