A Guide to Fraudulent Contracts for the Perfect Alliance

“I’m going to be rich—oh yeah—hmm-hmm.”

A swindler among swindlers!

I am Iris Plan.

It’s been 14 years since I met my mentor from the underworld and became the best con artist.

Now, for the ultimate heist of my life, I’ve decided to retrieve a hidden treasure from the Duke’s estate concealed within the Chester Count’s mansion.

I was only nervous about the notorious reputation of the count’s house as a casino king for a moment.

I successfully got myself hired undercover, and I figured out the location of the treasure.

Just in time, the butler, who seems to hold the real power in the mansion, also…

“Ha ha, isn’t the weather lovely?”

“It’s never a bad thing to see someone searching for something precious. Let me help you.”

He may have a handsome face, but he seems like a fool!

…Or so I thought.

“Put one of them down. Either your neck or that jewel.”

What the hell.

He was a rival who had infiltrated the mansion, aiming for the same treasure as me?
