- Robert Holmes: Jack, he's been parked outside since yesterday.
- Jack: Shepherd thinks his own mother's a spy. All I know is I put the decoder in your safe.
- Robert Holmes: Well, I'm sure he suspects you and I of stealing it - some nefarious plot to sell it to... well, whoever the bad guy is this month. In the right hands it could be worth millions. I could take all that money and buy a sports car like yours.
- Jack: What? An old man like you?
- Shepherd: You've never seen those names before?
- Robert Holmes: No.
- Shepherd: Hmmm. Well, they were found in your desk. I got permission from the ambassador to search your office - and Jack's.
- Robert Holmes: I am an Oxford graduate, you know. I'm not entirely dim. If I had stolen the decoder, do you think I would keep a list of the people I could sell it to in my office?
- Bo Sawchuk: You're saying Shepherd wants to frame your dad?
- Shirley Holmes: Shepherd's job is on the line if he doesn't arrest someone. He hasn't found the real culprit, so he could be setting up my dad to save his own hide.
- Bo Sawchuk: Yeah, but he's a spy catcher, not a spy.
- Shirley Holmes: You need to think like one to catch one.
- Shirley Holmes: I've ruled out all the possible fibers left normally by us.
- Bo Sawchuk: Maybe he wasn't wearing any clothes.
- Shirley Holmes: He's a spy, not a weirdo. There's no fibers, no footprints, no fingerprints on the linen closet. This guy gets in and out without leaving any trace.
- Bo Sawchuk: Why would Shepherd put a sheet on your dollhouse?
- Shirley Holmes: I don't know. Maybe he's an expert in psychological manipulation. Except he's made one mistake.
- Bo Sawchuk: What's that?
- Shirley Holmes: Underestimating me.
- Shirley Holmes: Sorry, Watson, you're staying in tonight. Would you rather bring a master spy to his knees or chase Mrs. Hughley's cat?
- [Watson whines at the door]
- Shirley Holmes: Figures. Chase the cat.
- Bo Sawchuk: I still don't get why he's doing all this weird stuff with the bird.
- Shirley Holmes: Some analysts say when you dream about a bird, you're going to get a letter. A dead bird means a coded or unreadable document - the connection to the decoder key.
- Shirley Holmes: Nothing but my left thumb print. I found my left fingerprints on the linen closet.
- Bo Sawchuk: So what? You live here. Your fingerprints are everywhere.
- Shirley Holmes: I'm right-handed. Bo, there's only one person who knew about the hidden staircase, who knew where the camera was, who had the motive, means and opportunity to break into this house.
- Bo Sawchuk: Who?
- Shirley Holmes: Me.
- Shirley Holmes: Maybe my unconscious self was sending messages to my conscious self - the bird, the sheet, the dagger...
- Bo Sawchuk: You carried them all with your...
- Shirley Holmes, Bo Sawchuk: ...left hand.
- [last lines]
- Shirley Holmes: And I found out that, like the staircase and the safe, my mind holds many secrets.
