Stacey Smith?

Stacey Smith? wrote The Church of Saint Sebastian in Short Trips: The History of Christmas, as well as several unlicensed fictional and non-fictional works about the Doctor Who universe, including Who is the Doctor, Who's 50: The 50 Doctor Who Stories to Watch Before You Die and The Doctors Are In: The Essential and Unofficial Guide to Doctor Who's Greatest Time Lord, with Graeme Burk.

The question mark after her surname is a legal part of her name. Thus she is properly Smith?, not Smith.
