Adrift on the Nile (Thartharah fawqa al-Nīl, Arabic: ثرثرة فوق النيل)[1] is a 1966 book by Egyptian author and Nobel Laureate Naguib Mahfouz.

The book follows Anis Zani who smokes kief every night with a group of friends on a houseboat on the Nile.

The book starts out with Anis Zani, the protagonist, being disciplined by his boss for submitting a blank report.

It's revealed that Anis wrote the report under the influence of drugs, which prevented him from realizing his pen was out of ink.

The downfall of the group is accelerated when, one night as they are taking a midnight excursion by car, they hit a person and flee the scene.
