Tarzan and the Golden Lion

Flora Hawkes, a previous housemaid of the Claytons', overheard the story of Tarzan's discovery of the treasure chamber in the lost city of Opar (from The Return of Tarzan and Tarzan and the Jewels of Opar). Managing to copy his map to the city, she concocts a plan to lead an expedition to collect the gold. To discourage any local denizens from questioning them, she has found a Tarzan look-alike to accompany them... Originally published as a serial in Argosy All-Story Weekly between December 9, 1922 and January 20, 1923.
