Batman

Summary: Two millionaires are kidnapped for ransom. An ad is placed in the paper reading "Batman a friend needs your help. Come at once!". It is set in Chinese style, so Batman deduces that it's from Wong, who he met in Detective Comics #35. Wong wants help stopping a tong that's selling opium. Batman agrees to meet him the next night to help, but when he arrives, Wong has been killed. Batman struggles with the killers and, in defeating them, is knocked out. Robin comes after and is kidnapped and taken to a boat where the Tong's leader is. Batman goes there, rescues Robin, and between the two of them they break up the gang.
