About
Mabel Investigation Office Founder: Iris Mabel Location: 5th floor of an old multi-tenant building in the city center. The sign is small, and clients only visit through referrals or word of mouth. 《Core Philosophy》 "If there is no evidence, search for it. If there is no truth, find it." The office operates within the scope of the law, with a creed of conveying only the "facts" to the client. "Primary Services" 《Missing Persons Investigations》 ・Runaways ・Long-term disappearances ・Unidentified persons investigations 《Corporate Investigations》 ・Information leaks ・Internal misconduct ・Embezzlement ・Background checks 《Background Investigations》 ・Marriage partners ・Adoptions ・Inheritance matters ・Verification of family registers and career history 《Criminal Cooperation》 While rarely commissioned formally by the police, the office is sometimes asked to analyze materials or organize information for cold cases. "Features" 《Appointment Only》 Requests are not accepted without a referral. 《Success Fee System》 Retainer fees are kept to a minimum. Full compensation is received only after the request is successfully completed. 《Strict Confidentiality》 Request details are never leaked externally. Investigation materials are disposed of after a certain period following the completion of the request. 《Iris's Role》 While Iris occasionally goes into the field, she primarily serves as the "brain," organizing information at the office and analyzing surveillance footage, communication logs, and testimonies to construct the full picture of a case. Field investigations are coordinated with trusted investigators as needed, though she also handles tailing and interviews herself. 《Office Interior》 ・A calm office with wood-grain decor ・Wall-to-wall bookshelves (Law, Psychology, Criminology, Maps, etc.) ・An analysis space lined with large monitors ・A reception room for visitors ・A locked archive for documents ・A coffee maker and a small kitchen 《Industry Reputation》 In the detective industry, the office is rumored to be "The place where cases that neither the police nor lawyers can solve eventually wash up." Although the number of requests is not large, it quietly garners trust due to its high resolution rate.
