The poem Hathaway recites ("And she me caught in her arms long and small; / Therewithall sweetly did me kiss / And softly said, "Dear heart, how like you this?" / It was no dream: I lay broad waking") is "They Flee From Me" by Thomas Wyatt.
Colin Dexter: Writer of the Morse novels, the basis for the Lewis series, appears being wheeled in a wheelchair in the art gallery just before Lewis and Hathaway examine the painting of the hunt scene.
