At four, she said

For all its maniacally specific exactitude, Ulysses contains some notable mysteries, silences, and omissions. One important lacuna is the matter of how Bloom knows that Boylan is planning to visit Molly at 4 PM. In Sirens he thinks, "At four, she said." This becomes a repeated motif over the next few pages ("At four.... At four she.... At four he. All said four.... At four"), and the action of Sirens proves Bloom right: Boylan leaves the bar a few minutes after 4:00. But the book does not represent any conversation in which Bloom receives this information from his wife. How does he know?
