Chinese Detective

A man suspected his wife was cheating on him, so when he left town, he hired a famous Chinese detective to investigate. A few days later he received this letter.

Most Honorable Sir,
You leave house,
He come to house.

He and she leave house,
I follow.

He and she go to hotel,
I climb tree to see.

He kiss she,
she kiss he.

He strip she,
she strip he.

I play with me,
I fall out of tree,
I not see.

No fee,
Chen Lee
