Wanting to raise her son in England, Linden decided not to pursue a career in Hollywood. She was considered for The Lion in Winter (1968) and The Go-Between (1970); the latter was for the lead role of Lady Marian Trimingham, for which Christie was later cast. She turned down the role of Amy in Sam Peckinpah's Straw Dogs (1971).
Linden toured in Trevor Nunn's Royal Shakespeare Company production of Hedda Gabler for two years playing Thea Elvsted, with Glenda Jackson in the title role; they later appeared together in the 1975 film adaptation.
