Chinese PI

A husband suspected his wife was seeing another man, so he hired the famous Chinese detective, Chen Lee, to investigate.

A few days later he received this report:

MOST HONORABLE SIR
YOU LEAVE HOUSE
I WATCH HOUSE
HE COME TO HOUSE
I WATCH
HE AND SHE LEAVE HOUSE
I FOLLOW
HE AND SHE GO TO 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
I NO SEE
NO FEE,

CHEN LEE
