A third, and differing account of Pepin's life comes from Notker the Stammerer, a Benedictine monk writing during the reign of Charles the Fat, the great-grandson of Charlemagne. Notker's account, referred to by modern scholars as the "Gesta Caroli Magni" ("The Deeds of Charles the Great") or "De Carolo Magno" ("Concerning Charles the Great") provides much more detail about Pepin's plot than earlier sources, although some of the story seems heavily inspired by classical sources. According to Notker, Pepin and his co-conspirators meet in the church of St. Peter in Regensburg to discuss their plot, where a cleric hiding under the altar overhears them. After the deacon reveals the conspiracy to Charlemagne, the plotters are captured, and Pepin is "cruelly scourged" and banished to a poor monastery—Notker claims that it was the monastery of St. Gall, although Pepin was almost certainly sent to the monastery of Prüm.
