As Number Six's return to Britain, which occurred on March 18, took approximately 30 days, he would have escaped from the Village on or around February 23.
Thorpe: And they're all... numbers? No names. No names at all?
Number Six: Just numbers.
The Colonel: I see.
Number Six: Numbers in a village that is a complete unit of our own society. A place to put people who can't be kept around. People who know too much or too little. A place with many means of breaking a man.
Thorpe: You resign. You disappear. You return. You spin a yarn that Hans Christian Andersen would reject as a fairy tale.
The Colonel: You're a stubborn fellow, Number Six.
Number Six: James, you call me that once again and you're liable for a bout in hospital.
Thorpe: Interesting fellow.
The Colonel: He's an old, old, old friend. Who never gives up.
Mrs. Butterworth/Number Two: [to Number Six] Many happy returns.
