Argonauts Agency: Golden Fleece

On a bright morning, as Jason, the chief of Argonauts Agency, was settled in his office, a disheveled man burst through the door in a panic. His agitation was so intense that his words were initially a jumble. Once the man regained his composure, he recounted the previous night's events in his mansion. An avid collector of ancient artifacts, he was horrified to discover that the Golden Fleece had vanished from his vault that very morning, along with his niece. The Argonauts Agency sprang into action without a moment's delay, tackling this enigmatic case.
