What is a Detective?

The job of a detective, who deduces clues from people's requests, murder cases, and mysteries, and sometimes solves cases by running around, exists in many places, but there are not many skilled detectives and detective agencies.

Jamie Opens a Detective Agency and Solves Cases

The detective agency run by Jamie pursues something different from ordinary detective agencies. From ordinary murder cases to errands, the detective agency mainly solves incidents and accidents caused by phenomena called 'monstrous' and other races. Only Jamie's detective agency and its rival agency, Monato Detective Agency, do this.

Monato Detective Agency

A detective agency that pursues the same goals as Jamie and solves cases. The name is Ruine Monato. Heron 's twin sister, Heshel, is her assistant. Since there are very few incidents caused by monsters, they often encounter each other when requests come in. She has excellent skills and personality, and she is a kind woman who sees Jamie as a rival and often helps.

Chapter 1: The Guardian Protecting the Crystal and the Cave

One of Jamie's daily routines is reading the newspaper that Heron brings in the morning. Although there isn't much, they can get some information, so while reading the newspaper today, a phrase caught their eye.

'The highest quality crystal comes from Mount Della in Wales! The crystal that used to come from there can no longer be mined!'

The article was very small and placed in one corner, but it seemed different from ordinary incidents.
The content of the article was as follows:

'Mount Della in Wales has been mining high-quality crystal for a long time, but since a few days ago, strange animal cries have been heard, and several miners who went inside have gone missing.
The police are struggling to investigate the case, but there is no progress in solving it.
Will the missing miners ever return?'

Jamie sensed that it was an unusual incident, but if the police were already investigating the case, Jamie couldn't interfere first, so they were hesitant. Just then, a letter arrived.
The recipient was Pearlgaun Brown, a police inspector.

'To Detective Jamie, miners have gone missing at the Mount Della mine in Wales, along with strange animal-like cries.
I am investigating the case with my junior, Leviton Harberwell, but there is no progress, so I thought your help would be needed and wrote this letter. I have enclosed a train ticket to Wales, so please solve the case.'

Jamie felt like the problem they were worried about was being solved smoothly and immediately started packing.

Chapter 2: Screams Echoing in London and Jack the Ripper

Jamie and Heron , who successfully solved the Mount Della case, were preparing to return home when Pearlgaun, a police inspector from London, approached and asked if they were returning to London. Pearlgaun hesitated for a moment and asked if they could join them, and Jamie readily agreed. On the train to London, they heard the story from Pearlgaun. A serial murder case is currently occurring in London, and the culprit is Jack the Ripper, a serial killer targeting women. They entrusted the solution of the case to Jamie.
