You will need to provide your own maps of a city, castle, and buildings.

The Blues Company
	The city of ________ has been plagued by an abundance of thefts lately.  Items stolen range from children's lollipops to expensive gold and jewels.  The city guard has been keeping a close eye out for the culprits.  The only clue has been blue handkerchiefs left at the crime scenes.
		------------------------------------------
	Blues Company  This is a close knit band of thieves posing as merchants.  They get their name from the midnight blue cloaks they wear.  Their emblem is a blue and red teardrop.  Their cover is as a trading company.  They are very good traders (but better thieves).  The person in charge of all of this is an elf named Armius Bontonstine.  He is a 12th level fighter and a 8th level thief.  Bontonstine runs the operation with an iron fist.  He has 2d12 traders/thieves working for him ranging from 2nd level to 6th level.
		-----------------------------------
	The party is approached by someone they have done work for before.  Place this event somewhere in the city.
	*"Ah, my old friends," ________ says with a smile.  "Welcome to _________.  You're  Just in time for the celebration.  The Jewel of Simcod will be presented to the king tomorrow night."  If asked about the Jewel of Simcod, he replies, "The Jewel of Simcod is a priceless diamond.  Some believe it to be worth around 200,000 pp in value.  The jewel is as big as a horses head and is perfectly cut.  You know, since you did such a fine job for me, I might be able to get you in to see the ceremony.  Meet me at the castle gate about sundown."
	The party is free to do as they wish around town.  Everywhere they go they hear about the jewel.  If they ask about it, they get all sorts of answers like:  "The Jewel of Simcod, I hear it is very valuable.  It's worth (x) pp" (x being anywhere from 2000pp to 2,000,000pp).  They hear all sorts of sizes to the jewel.  Also allot of people are worried that whoever has been committing the string of thefts around the city will try to steal the Jewel of Simcod.
	In fact, Bontonstine is already making plans to steal the jewel.  He has two of his best men working on it.  They are going to set it up so four buildings in town will explode at the same time.  Then, when the guards leave for the fires, they will cast magical darkness over the jewel and make it disappear.

	*The castle is a bustle of activity for the event.  As the party approaches the gate they are met by their 'friend'.  "Well met," he says, "I have your invitations here.  Oh, and to let you know, the security is tight here tonight."
	*He leads the party to the gate.  "Invitations, please,"a guard says.  He looks over the invitations and then looks at the party.  "Weapons, please."  Their 'friend' pulls out and hands the guard a short sword and a dagger.  If the party refuses, the adventure ends there because the guard refuses to let them enter.  If they hand over their weapons , the guard lets them pass.
	As they enter the castle, they hear the sounds of a celebration.  Bontonstine is there to make sure the heist goes off correctly.  As the party mingles they are offered drinks.  About two turns later the music starts and the king and a richly dressed foreigner steps out on the stage.  Behind them are three burly looking guards that are carrying a large chest.  The chest is decorated with jewels and gold.
	*The king looks at the people assembled and speaks.  "My good people.  The Kingdom of ___________ has come to us with good tidings and wishes for peace to our two lands.  As a token of this peace, they bring us a gift, the Jewel of Simcod."  The guards open the chest and the king pulls out a huge diamond."
	About that time some explosions are heard.  Most of the guards run out of the chamber.  As soon as they leave, a magical darkness falls upon the room.  There are some screams and about two minutes later the darkness is gone.  On the stage, the king and his guest are laying on the floor unconscious and the guards have been stabbed in the back.  The diamond the king was holding is gone.
	Someone runs up on the stage and wakes the king up and tells him what happened.  When the king and his people investigate they find a blue handkerchief in the box.  At that point he turns to the crowd and says, "My good people, if anyone can provide information leading to the return of the jewel and the capture of who is responsible for this or bring them in, I will personally make it worth their while.  Please, if you know of anyone that could help, send them to see me."

Events
	1. Castle.  Come up with a castle map.  On the stage where the king was is found a blue handkerchief in the chest, a blue and red teardrop necklace, and two darts laying near the spot where the two men where knocked out.  The darts have a sleeping potion on the tips.  The necklace is found next to the chest.  If Bontonstine is asked why his companies emblem is there, he explains that one of his men must have dropped it in the confusion.
	2.  Main Street.  The party is walking down the street when they hear a scream.  If they investigate they see 1d4 city guards running into a building.  The building is a gem shop and 2000 gp worth of jewelry has been stolen.  In the vault, that was locked, a blue handkerchief is found.
	3.  Random place.  Make sure the party is present.  The party catches a thief in the act of stealing something (make up something).  Let them capture him.  When he is captured, he bites down really hard on something and falls over dead.  What he bit down on was a small capsule.  On his body they find a blue cloak, a blue handkerchief, a lock pick set, 50' rope, a +1 dagger, bracers AC2, and a blue and red teardrop necklace (hmmmm....).
	4.  Random events.  Come up with some other crimes during all this.  Don't leave a blue handkerchief at all of them.  Try to keep the party guessing.  But let it lead up to the Blues Company in the end.  The closer the party gets to solving this, have assassination attempts happen to the party.
	5.  The Blues Company.  When they enter the Blues Company they are greeted by a well dressed man.  "I am Johann Roxilin.  How may I be of service?"  If the players do this right they will ask to see whoever is in charge.  Roxilin leads them to a room, "Please wait here while I go and get Mr. Bontonstine."
	Once they enter the room, the door shuts behind them.  They notice a strange odor.  Save versus paralyzation or fall asleep for 3d6 rounds.  After the sleep gas, 2d8 men (4th level fighters) enter the room and start attacking whoever is standing still.  If the party is defeated they are taken prisoner.  Let the party win if they make the save.  Bontonstine is so sure of his men that he does not send anymore (yet).  The party finds the treasure but Bontonstine escapes.  When they find the treasure 2d12 city guards (6th to 12th level fighters) come barging into the room.  The king had someone following the party and is making sure they do not try to take anything.
	In conclusion,  King ______ offers his gratitude, 1000 gp - 5000 gp (up to the DM), three jewels at 500 gp each, and a +2 short sword.  For fun you may substitute a cursed sword for the +2 one.  The party also gets 6000 experience for the adventure.

	I will work on a higher level campaign involving Bontonstine wanting his revenge for the party stopping his plans.  If you have any ideas for this, please E-mail me with the basic plot.
