Discord in the house of Pi
But before Castle can have his treasure-hunting fun, he has to deal with the unpleasantness of his daughter and her fruitarian beau.
Alexis and Pi have moved in together and are happily living the Bohemian lifestyle, dumpster-diving for furniture and chasing bees for profit. Of course, Castle isn’t too happy about the fact that his daughter has moved in with an idiot.
Too bad for Castle that this is half about Alexis feeling the need to punish her dad for diving into an engagement with Beckett. Because Castle didn’t wholeheartedly approve of Pi (and seriously, who would?), Alexis has now decided that her dad can’t be part of their lives.
In other words, Alexis has suddenly turned into something of a b****.
Accountants are rarely crucified
Fortunately, Castle has murder to take his mind off his daughter’s annoying and self-destructive behavior. A pretty young accountant named Susannah Richland has been killed, her body laid in an alley like she’d been crucified. Adding to the oddness, the cause of death was a sword through the neck.
A look into her life yields nothing other than some books on medieval history and an unexplained interest in occult symbols.
Latin clues and mysterious monks
Surveillance footage reveals that a man in a monk’s habit was following Susannah on the night she died. The police are able to identify the man as a reformed felon turned religious man. Although the brother insists that he was only trying to keep the woman safe from some strange man that was following her, the whole thing seems suspicious.
It’s especially suspicious if you take those occult symbols to mean some sort of “Da Vinci Code”-style conspiracy is at work.
The mysteries only grow when Castle and Beckett find out that the victim consulted a professor on the symbols and on a letter written by a late 18th-century member of the Freemasons. Castle’s rusty (yet extremely impressive) Latin skills reveal cryptic clues that may just lead to some sort of treasure. A “National Treasure” even …
After finding some clues in the monks’ chapel, Castle and Beckett head downtown to an authentic blacksmith’s shop that has apparently been there since the 18th century. Zorro is waiting.
No really. There’s a guy wearing a Zorro mask who challenges Castle to a duel with swords. This may have been a mistake on the part of Zorro — Castle is actually very good at fencing. In a fight worthy of Inigo Montoya and the Dread Pirate Roberts, Castle pins Zorro and demands information.
He may not get the information he wants though.
At the first mention of murder, Zorro withers into a terrified actor used to working Renaissance fairs. He was just hired to pass out clues to people playing the scavenger hunt.
The game’s afoot
Yes, that’s a scavenger hunt. The whole conspiracy and all of the strangeness surrounding the murder can be reduced to a game.
A man named Nolan Burns has organized the scavenger hunt as part of a fundraiser for the New York Historical Institute — Susannah Richland was one of the participants. It shouldn’t have been a big deal, but somehow the accountant ended up dead.
Looking at the participants, the cops find out that there is one man who seems especially suspicious. Registered under a false name and wearing dark glasses in the photos, this guy also happens to fit the description of the man following Susannah that the monk gave.
All this over a dime bag?
Poor Castle. He really wanted this to be a vast conspiracy eventually leading to treasure, and he gets is a scavenger hunt.
Or is it? Castle combines the various occult-ish symbols with a final symbol that Susannah drew on her own hand before she died. When all of them are together, the result looks just like the stone decoration on the wall of the monastery’s chapel.
The sculpture even has a face with a gaping mouth. While sticking his hand in the whole doesn’t lead to being eaten by a monster, Castle does open a hidden door. It’s kind of awesome, actually. Inside the door is a tomb that shares much of the iconography seen throughout the hunt.
It wasn’t just a game! There’s even a sarcophagus that opens via hidden tricks to reveal … A large bag full of dimes? According to the show, these dimes (or half-dimes or whatever they are) represent the first money coined in the early United States after the Revolutionary War. They’re really, really valuable as a result.
It’s not all treasure in the tomb though. Right next to the sarcophagus lie a sword and a pool of dried blood. This is the murder scene.
And then there’s the booby trap. When Castle lifts up the bag of coins, a stone block descends (in an awesomely Indiana Jones style) and the tomb door slams shut. They’re trapped! Of course, being trapped in a strange location is nothing new for Castle and Beckett. All it takes is a few bars on Beckett’s cell phone, and they escape from this one.
“The Da Vinci Code” for the Kickstarter age
So who is the murderer? The detectives first think it’s Burns, the scavenger hunt organizer. While the man is guilty of creating the hunt in order to solve the riddles in Theodore Rose’s 18th-century letter, that’s all he did. His connection with Susannah even has a simple explanation: She’s a descendent of Rose and the family had legends about the man.
It makes sense then that family might be in on the murder. It turns out that Susannah’s cousin knew that she was going after the old family treasure. He was even tracking her moves, disguised as the mysterious scavenger-hunt man. But Susannah didn’t want to profit from the treasure, and that’s when her cousin snapped.
If he couldn’t have the money, then it would stay hidden. Needless to say, this is not a nice guy.
In the end, the monastery donates the coins to the people. Castle gets to find a treasure. And they all live (except the murder victim) happily ever after.
