Stealing chemicals from Kinzo's study [EP5] Form of four tea cookies. 3/4 remaining.

"After all, Kinzo-san's study is a treasure vault with all kinds of chemicals! I obtained all sorts of results to create an ultimate truth, infinitely close to a red truth. This isn't a science mystery, so I'll spare you the details."
As Erika swaggered around the cathedral, she arrogantly touted her scientific knowledge.
She had thorough knowledge of all the chemicals in Kinzo's study and had used them to conduct a scientific investigation, which had now been acknowledged and made into a red truth by Bernkastel.

......She didn't explain the details, but she had obtained results that were convincing even without the red truth.
Collecting fingerprints with aluminum powder.

Component analysis of the mud under someone's shoe and various chemical reactions from the clinging rain water.
......Erika just walked into someone else's study several times and used several chemicals however she pleased, all without asking the family's permission.
However, no one could fault her for this.

The pieces couldn't hinder any action the detective might take for the investigation.

That's the power of the detective's authority.

At some point after they broke into the study Erika went back there and took all his useful chemicals and stuff.

This is an extremely trivial memory, especially at this point.
