Jake: How could the best detective that Holt's ever worked with make such a mistake? I wondered myself, so I made a few phone calls. It turns out, Dillman was fired by the SFPD. I guess he rubbed the brass the wrong way. Not only that, but he's currently working part time at Yarn Barn, a hobby shop in Albany. I have his manager on the phone right now.
Alyssa: [on Jake's phone] Frank, what is going on? You have a shift tonight. You know I have finals.
Dillman: [stammers] I'm so sorry, Alyssa. I got hung up in the city. I just lost track of time.
Jake: This explains everything. He's not a great detective. He's a sad man working part time selling crafting supplies.
