The doctor who tried to save the Gul sisters, Dr. Khaled, produced a patient ledger for the past two months. As he pored through the list, he uttered the names of several young women who had attempted suicide: Fatima, Mariam, Zulfiya, Zar Gul, Basbibi.

“There are probably 200 cases in here of attempted suicide,” said Dr. Khaled, who goes by a single name, waving the ledger in the air. “In the last 12 hours, we had three.”

Perhaps no case is more emblematic, or more discussed, than the deaths of the Gul sisters.

The two came from an educated, progressive family. Mohammed Gul, their father, is a prosecutor. Nabila was on the cusp of graduating from high school, and planned to attend college in the city. Fareba was already attending college and hoped to follow her father’s footsteps into the legal profession. The young women were determinedly modern, and would not have seemed out of place in many Western cities.

Nabila was impetuous, with a quick temper and a strong sense of self. She often challenged what Fareba told her, rejecting the deference held for elders in Afghan society. Fareba, a softhearted woman who often wept after small arguments, confided to a close friend that she felt Nabila did not respect her.

Their last fight, the morning of Nov. 26, involved a boy Nabila said she was in love with. Fareba thought the relationship was inappropriate, and urged her sister against it. Nabila refused, and the two began shouting.

Their mother heard the fight, and ran in to break it up, slapping Nabila twice across her face for talking back to her older sister, according to people close to the family. The younger girl ran off in tears.
