My Best Friend Is the Number One Detective in Beijing.

I killed someone. The one who died was my fiancé. The evidence is conclusive and cannot be defended. Everyone was waiting to see my joke - the most useless lady in the capital finally committed suicide. Only my best friend, Su Tang, the number one detective in the capital, had his official seal photographed in the courtroom: "I'll take this case. My best friend, I'll try it myself."
