Mystery Synopsis:

Mancy Crew is a senior at River Peak High School. With a natural talent for investigation, she founded the River Peak High Forensic Science Club, which has even assisted the police department on occasion!

Mancy recently received word from an anonymous tip about a secret society called the Sisterhood of the Dangerous Secrets. This organization was founded in the 1920s at River Peak High, and membership has passed down generations ever since. This year, the Sisterhood has threatened to strike again! Mancy has called an emergency meeting of her team to discuss the mystery of the Dangerous Secrets. Supposedly, one of the club members is the target of a hidden secret!

Mancy has asked the forensic club to assemble in the teacher’s lounge of River Peak High. She will give the group details about the anonymous tip, but she also has a few stress-relieving games planned to break up the meeting. As Mancy says - relaxed sleuths are effective investigators! Rumor has it there are codes to break and riddles to solve before the hidden secret can be found somewhere in the school. Also, the anonymous tipper has hinted that someone in the forensic club may be a member of the Sisterhood of the Dangerous Secrets! The group will need to rally together to find the secret and find the member of the Sisterhood!

    Great Party Idea!

    My daughter's group of pre-teens had such a great time with this party! It was the talk of 5th grade for weeks :). The kit is complete and easy to follow, with tons of room to make this a one-of-a-kind party.
