She disappears after he draws the curtain, but as a former magician's assistant, uses the opportunity to escape. Police Inspector Farraday takes Blackie into custody as an accomplice, but Blackie easily gets away himself.
A trip to the library reveals that Dinah was sent to prison for three years for a robbery that netted $100,000 (which was never recovered) and a dead victim. Her magician former husband, John Lampau, was acquitted. Blackie tracks Lampau down, still performing magic, but now under the name of Jani, to warn him. Dinah shows up minutes later, having heard that Jani intends to marry his new assistant, Irene. Dinah has come to make sure she gets her half of the loot. In a scuffle, she grazes Jani's right hand with a gunshot before fleeing. Blackie arranges to impersonate Jani, while the magician hides in Blackie's absent friend's apartment.
That night, Blackie is awoken by sounds in Jani's apartment. When he investigates, a woman runs out of the unlit room. 
Blackie eventually locates the money in Jani's safety deposit box and takes it, still disguised as Jani. Outside, Dinah forces him at gunpoint to give her the envelope containing the loot, but when she opens it, it is empty. Blackie had taken the precaution of pocketing the money. In the meantime, Blackie's friend returns home from a trip early and finds Jani's body in the closet. Farraday corners and arrests Blackie and his sidekick, "the Runt" (George E. Stone), for murder. Blackie easily escapes from his cell.
