From a July 14, 1985, article in the Bergen (NJ) Record:

"Deceptions and Florence Nightingale paid me more in 10 weeks [of filming] than 2 1/2 years ofSherlock Holmes," Brett said. He got $97,500 for Sherlock Holmes, and $101,400 for Deceptionsand Florence Nightingale.

So if you ever wonder why quality English actors like Brett, skilled in Shakespeare and other rarefied roles, so often accept work in potboiler American mini-series and telemovies, now you know. Everybody has to pay the rent.
