Case 004
The case
Detective Lomdi and her assistant Chintu were examining evidence inside a research laboratory when a violent storm began. Suddenly, the electricity went out. The laboratory became dark, and all the machines stopped working. "The electricity may take a long time to return," Chintu said with a yawn. "Why don't we sleep for a while?" Detective Lomdi agreed—but they needed to resume their investigation the moment the electricity returned.
