Who does Britten want to be picked up for questioning in Native Son?

Henry Dalton's hired a private investigator by the name of Britten to look into his daughter, Mary's, sudden disappearance. It isn't very long before Britten suspects Bigger of having something to do with it. It doesn't help Bigger that he's acting all suspicious when he meets Britten for the first time. Nevertheless, Britten is still on Mr. Dalton's payroll, and as Mr. Dalton's convinced that Bigger had nothing to do with Mary's disappearance, Britten starts pointing the finger at Jan, one of Mary's Communist acquaintances. It looks like the only way that Bigger's life can be saved is by framing a Communist.After being brought in for interrogation by Britten, Jan doesn't help his case by lying about his movements on the night of Mary's disappearance. This makes him look suspicious, which takes some of the pressure off Bigger's shoulders. Realizing he's in serious trouble, Jan storms out of the house angrily. It's then that Britten assures Mr. Dalton that the police will pick Jan up and hold him for questioning.
