The young pulsar PSR J1740–3052, discovered in the Parkes Multibeam Pulsar Survey, is in a highly eccentric 8-month orbit with a companion of at least 11 solar masses. The up-to-date timing solution for this pulsar incorporates effects likely due to the spin mass quadrupole of the companion star; we discuss the implications for the geometry of the orbit. The pulsar signal displays increased dispersive delays as the pulsar passes behind its companion, indicating an interaction with the companion wind.
