Kaito sat at his desk. The lamp was low. The city outside was quiet.
He had the notebook open. Fifty pages. Fifty days.
Each entry was the same format. Date. Time. Location. Duration. Entity type. Outcome.
He had written them in order. He had never looked at them all at once.
Tonight, he did.
He spread the pages. He aligned the dates. He drew a line connecting the intervals.
The line went down.
Kaito thought: No.
He checked the math. He checked the dates. He checked his handwriting.
The line still went down.
Day one to day ten: average interval, forty seven hours.
Day eleven to day twenty: average interval, thirty nine hours.
Day twenty one to day thirty: average interval, twenty eight hours.
Day thirty one to day forty: average interval, nineteen hours.
Day forty one to day fifty: average interval, eleven hours.
Kaito thought: That is not random.
He stood up. He walked to the window. He looked at the Grey District.
It was dark. Nothing moved.
