Tumnus' flute

Tumnus's Flute was a flute that Mr. Tumnus played for Lucy when she first visited his cave shortly after arriving in Narnia. The music of the flute put Lucy to sleep. Tumnus had intended on then turning her over to the White Witch - a plan which he decided against, much to his own danger, as he was risking being charged with treachery against the White Witch for not turning reporting the appearance of humans in Narnia.
