Reading

I finished reading "Tokyo Electric Power Co., Inc. female office worker murder case" today. This book is a documentary. The victim was an elite female office worker who was killed at 38 years old. At the same time, she was a prostitute on the street every night. At the time, a Nepalese was arrested on suspicion of robbery-murder. But after 3 years his suspicion cleared and he was acquitted of murder. The true criminal was not founded yet. I was interested in her thoughts. Why did she sell sex everyday after work even though she had high salary? And she went home by the last train every night without exception, we don't know why. After all, as the author said, I also don't know about her at all.
