Can you help our Lead Detective solve the crime before it's too late?

June's Case

Case 009: Part-Time Thieves

Rei Yukimura has spent months organizing this year’s annual Dayton Asian Festival. She thought it was going to be perfect until her daughter learned that a group of kids from her high school have been hired to steal from the vendors.

If word gets out that a group of thieves intend to descend on the festival, it will be ruined. Who hired the kids is a mystery, but Sullivan can’t exactly skulk around the school looking for answers. Instead, he has to rely on Rei’s daughter to be his eyes and ears on the inside. Can you help Sullivan stop them and save Rei’s festival before it’s too late? Sign up today to find out.

Meet The Kings

Founded by Samuel King in 1961, Sleuth Kings has been a family-run investigations firm for three generations. Throughout that time, the King family has made it their mission to uncover the truth and help their clients get the justice they deserve.

Samuel King

Never one to stand by while someone is in trouble, Samuel began acting as an amateur investigator in the mid 50’s. As his skills improved and word of his successful investigations spread, Samuel decided to officially create Sleuth Kings and investigate full-time. In 2004, he finally decided to retire and passed Sleuth Kings on to his son, Isaac.

Isaac King

Isaac began working with Samuel in 1980. He quickly learned his father’s techniques and worked to bring new ideas and innovations into Sleuth Kings. In 2004, when Samuel retired, he became the lead investigator and went on to solve several high-profile cases until he went missing in early 2017. The investigation into his whereabouts is still ongoing.

Sullivan King

Fascinated with the idea of being a detective, Sullivan officially began working with his father and grandfather in 2003. When Isaac disappeared in 2017, Sullivan closed public investigations in order to look for his father. Under Samuel’s guidance, Sullivan has decided to reopen Sleuth Kings so he can help others. He continues to look into Isaac’s case, but makes helping the people of Dayton his top priority.
