What is a short summary for the story, Madame Rosette?

Stuffy, Stag and William are three RAF pilots who go into Cairo on a forty-eight-hour leave from combat in Libya looking for women. They encounter Madame Rosette, an exploitative and predatory whorehouse operator who keeps her "girls" in near-slavery. The three soldiers are outraged at the injustices perpetrated on the young women forced to sell themselves to survive. Instead of buying their services, the men decide to lock Madame Rosette in her office and to let the prostitutes escape her clutches. They buy the women drinks and then carry them each home in rented horse-drawn carriages. All three are rather simple yet honest young Brits whose sense of injustice is stronger than their lust or the effects of alcohol.
