When the goddaughter of a mobster is murdered, the mobster (José Quintero) offers to have his gang investigate the crime and come up with a suspect. But anything the Mob does as a favor carries a price, and though this particular price is never stated, Mary Beth Lacey is adamant about refusing the offer and pursuing the killer through the regular legal channels. When Cagney and Lacey do find the killer through standard procedures, the mobster drives up to them, thanks them through his car window - and drives away.
