It's long past time for another Who's Round, Toby Hadoke's Doctor Who 50th anniversary quest to get an anecdote about every single episode of Doctor Who to date. In this instalment, Toby asks whodunnit.
Whodunnit this week? Yes indeed: a character actor whose career has lasted as long as Doctor Who itself but who only appeared in it relatively recently. On the menu - the similarities between Frank Windsor and Paul Schofield, wearing a false head and being quintessentially English.
