British thriller author Eric (6)

I believe the answer is:

(Other definitions for ambler that I've seen before include "Eric, thriller writer" , "Eric -, English author (The Mask of Dimitrios)" , "Leisurely walker" , "Horse" , "one moving slowly" .)

I've seen this clue in The Wall Street Journal.
