What is the total number of films in the "Thin Man" movie series?

"The Thin Man" is a series of six popular films featuring detective characters Nick Charles (William Powell) and Nora Charles (Myrna Loy). The first film was based on the novel "The Thin Man" by Dashiell Hammett. The actual films include: "The Thin Man" (1934), "After the Thin Man" (1936), "Another Thin Man" (1939), "Shadow of the Thin Man" (1941), "The Thin Man Goes Home" (1945), and "Song of the Thin Man" (1947).

This series often, called 'sparkling' and 'irresistible' by critics and fans, featured the sleek chemistry of Powell and Loy as husband and wife sleuths. They solved murders with the aid of their wire-haired terrier, Asta. Set in the glamorous world of 1930s upper-class Manhattan, the films ("The Thin Man" and its sequels), accordingly to movie pundits, established a standard for witty comedy, clever dialogue, and urbane one up-man-ship.

Among the series' many attributes, it was publicly noted that one of its most radical notions was the idea that "a married couple might find each other delightful and view life as a goofy adventure together".
