Tarzan and the Lion Man

Tarzan and the Lion Man (Edgar Rice Burroughs Authorized Library)
 
Book 17 of the Tarzan Series - Special Edition Authorized by Edgar Rice Burroughs, Inc.
 
A great safari comes to Africa to make a movie, struggling across the veldt and through the jungle in great ten-ton trucks, equipped with all the advantages of civilization. But now it is halted, almost destroyed by the poisoned arrows of the savage Bansuto tribe. There is no way to return. Ahead lies the strange valley of diamonds, where hairy gorillas live in their town of London on the Thames, ruled by King Henry the Eighth. And behind them comes Tarzan of the Apes with the Golden Lion, seeking the man who might have been his twin brother in looks—though hardly in courage!
