Task: Question Generation
Input (English): Passage: The drama begins with a murder and a screaming witness.  The witness to the crime tells the police that she can identify the murderer and will never forget his face.  Mob attorney Walter Colby is called by crime boss Hap Richie in the middle of the night to arrange the release of Caesar, one of his mobsters arrested for the murder.  After Colby does so he tells his girlfriend, the unscrupulous mob-connected showgirl Flaxy Martin, that he wants to quit the organization and become respectable.
Meanwhile, the syndicate arranges for Peggy Farrar to falsely testify on behalf of Caesar.  After Caesar is cleared of the charges, however, she changes her mind.  Flaxy and Caesar go visit Peggy at her apartment to force her into silence, and Caesar ends up killing her.
Due to circumstantial evidence, Flaxy is suspected of murdering Peggy. Not realizing her involvement in the killing, Colby tells the police that he did it, his plan being to defend himself so well that he gets both himself and Flaxy off.  Unfortunately, Flaxy and Hap Richie set him up during the trial and Colby is sentenced for Peggy's murder. As Colby awaits transportation to prison, Sam Malko, a friend of Colby and a former client, tells him that Caesar had been getting drunk and bragging that Colby was sentenced for a killing (the murder of Peggy) that he (Caesar) committed. Sam wonders why Flaxy was not helping Colby since she must know the same information.
On his way to prison to serve 20 years, Colby escapes and when he gets to the highway he passes out in front of motorist Nora Carson.  Nora helps Colby get to the city to find out how he was framed. Colby realizes that Flaxy was not the woman she pretended to be.
Output (English): Who does Sam Malko tell Walter Colby has been bragging about killing Peggy Farrar?
