Jack is calling the Savoy and asking for Mia -- under the watchful stinkeye of Ralph -- and asking if she got his package, and all I can say is Jack wishes she got his package. When he's done working on his love life, Ralph tells him Pete Holm has no knowledge of Merrick's mistress. "We've gotta find her. Mistress equals motive," says Jack. I love how these two cowboys -- well, at least Ralph was an MP -- are full-fledged Dragnet officers already.
Yvonne suggests calling a jewelry store because a man with a mistress buys jewelry and asking for the address Merrick was sending it to. Next thing we know, the Lamb brothers are being shot at from behind a closed door by a panicky redhead who drops the gun and then bolts, grabbing a suitcase while screaming over top of the wacky caper music that's playing. She fearfully tells them she'll double whatever Nicky's paying them. That would be Nicky Tomisano, the redhead's husband. She says he killed Merrick, and she knows she's next.
Over at the Savoy, Rizzo's placing bets at the bar when Diane strolls over to tell him she talked to her lawyer, who is going to straighten everything out. Elsewhere, undercover deputy Dixon is snooping around and comes across man in storage room picking up boxes. He bolts when Dixon comes in, and Dixon yells, "Stop! Sheriff's department!" immediately, like SO MUCH FOR YOUR COVER. He loses the guy, but finds a door key left in the lock.
Ralph's questioning Tomisano at the sheriff's office, who's playing the "my wife's a slut and I don't care who she bangs" card, adding that if he killed the guy responsible for mob construction, he'd be in the ground next to him right away. His wife is dealing with Jack, whose excuse for shooting at the Lambs is that she thought she was shooting at someone else (her husband). She was on the outs with Merrick anyway, since the ingrate left her for a candystriper at the hospital named Amy Seger.
Turns out she's got a record: aggravated assault, narcotics use and sale. Hardly the kind of person you'd find with a respected businessman, says Jack. Jack, you'll recall, was just interviewing this respected businessman's previous girlfriend, a gangster's wife, so that line makes zero sense, except to set up Ralph as they roll up on Seger's address: a church. "Hardly the kind of person you find here," he says.
Inside, there's a full-on revival going on, singing and clapping. The woman preacher at the front is conspicuous by her gender, this being television, so it's not a surprise when Ralph asks a woman in a back pew where Amy Seger is, and it turns out she's the preacher.
