2:00 Nick Maddock is whom the coffin is being purchased for. Andrew Grollo is the gangster buying it.

3:04 Logan calls the casket a "silver-plated slumber box." Earlier, 1:37 the gangster called it a "plush-lined box."

5:20 Maddock calls Logan asking if they have heard anything; Grollo and his gang walked into the police station! This gives them an alibi for the Maddock killing.

7:38 Casey says that they "may find the point" at Maddock's apartment. He sure does. At 13:01 Casey steps on a thumbtack. Whenever something innocuous and nonsensical happens, Cole has placed it there for a reason.

While Casey and Ann are talking to Inez at Maddock's apartment, she's arguing with Maddock and says she's standing by a doorway. She's putting herself in the right position so as not to get in the way when Maddock gets shot.

10:25 She mentions she grew up in a mill town and that her father was a weaver. That's important later.

10:38 Nick Maddock is shot!

14:02 Officer Bernstein finds fishing line outside, some of it tied in a "sheet bend knot" It is assumed that whomever killed Maddock was in the Navy at some time, where that kind of knot would be taught and used.

15:30 At the Blue Note, two weeks have passed without any resolution to the case. Ethelbert says he knows how to make the knot because his mother taught him, except to her, it was called a "weaver's knot."

All of this leads to Casey's theory that Inez, Maddock's girlfriend, created the combination of fishline, thumbtack, and gun, to give her an alibi because she could execute the plan in plain sight of people who would be her alibi. In this case, Casey and Ann. It was also coordinated that Grollo's gang would all be in jail at the time of the shooting. The rope ladder outside the building was used as a decoy.

20:25 Ann turns on the light in Inez' apartment, and Grollo is there looking for evidence, too. 20:54 There's a gun in the room, as Ann says "we're always willing to help a man who has a gun pointed at us." They're all looking for a clamp that held the gun. Grollo says she made him sign an incriminating letter.

22:07 Inez and Grollo shoot each other convinced that one double-crossed the other.

Ann calls Ethelbert a "skinker." The word means "someone who pours liquor." In recent years, there is a vastly different and more obscene definition, which could cleanly be described as a "woman on the prowl for a man." Casey says "skinker" is also a kind of lizard, which is correct.
