The following article contains an answer for the question: Who plays the character that the business partner of Nita's boyfriend is trying not to be seen by? , can you please find it? 

On an ocean liner sailing from the Orient to San Francisco, Mei Lei Ming gives fellow passenger Nita Kenton a reading. When Nita's boyfriend, importer Phillip Corey, scoffs at her predictions, she informs him that he himself will die within 48 hours.
Corey is later found dead in his San Francisco shop, an apparent suicide. Police Inspector Jim C. Gregg is certain it is a homicide and has Sergeant Kelly bring Mei Lei in for questioning. She convinces him she is innocent and, after demonstrating her astrological powers by telling both skeptical policemen about themselves based solely on their birth dates, proceeds to help them solve the case and two subsequent, related killings. Police forensic scientist Dr. Merton, however, remains firmly scornful of Mei Lei's unscientific methods.
When Corey's Chinese business partner Frederick Gow shows up at the police station, he recognizes Juggler Barrows (an uncredited Sidney Bracey), who has been brought in for questioning about an unrelated crime. He pretends to cough and uses a handkerchief to conceal his face from Barrows as he enters Gregg's office. There, he announces that he wants to recover certain business letters from Corey's safe. Mei Lei becomes suspicious. When the letters Gow wanted are later examined, Mei Lei discovers a coded message that indicates Corey and Gow were involved in drug smuggling.
