The Black Bag is a lost[1] 1922 American silent mystery film directed by Stuart Paton and starring Herbert Rawlinson.

It was produced and distributed by the Universal Film Manufacturing Company.

[2][3] As described in a film magazine,[4] wealthy Dorothy Calender (Valli) withdraws a string of pearls from her uncle's keeping to assist her brother with a debt.

Billy Kirkwood (Rawlinson), who thinks Dorothy is a thief but wants to save her from her folly, secures the pearls from the escaping crooks and restores them to the young woman.

Later it develops that the detective is dishonest and the whole gang is locked up, while Dorothy declares her love for the man who saved her property.
