Query: Existence de points fixes enlac\'es \`a une orbite p\'eriodique d'un
  hom\'eomorphisme du plan   Let f be an orientation-preserving homeomorphism of the plane such that f-Id
is contracting. Under these hypotheses, we establish the existence, for every
periodic orbit, of a fixed point which has nonzero linking number with this
periodic orbit.
