A Famous Chinese Detective

"A man suspected his wife of seeing another man.
So, he hired a famous Chinese detective, Ram Pam Sim Wimm,
to watch and report any activities that might develop.
A few days later, he received this report:
Most honorable sir:
You leave house.
He come house.
I watch.
He and she leave house.
I follow.
He and she get on train.
I follow.
He and she go in hotel.
I climb tree-look in window.
He kiss she. She kiss he.
He strip she. She strip he.
He play with she. She play with he. I play with me.
Fall out of tree, not see.
No Fee."
