We present new imaging and spectral data for globular clusters (GCs) aroundNGC 4365 and NGC 4342. NGC 4342 is a compact, X-ray luminous S0 galaxy with anunusually massive central black hole. NGC 4365 is another atypical galaxy thatdominates the W' group of which NGC 4342 is a member. Using imaging from theMegaCam instrument on the Canada-France-Hawaii Telescope (CFHT) we identify astream of GCs between the two galaxies and extending beyond NGC 4342. Thestream of GCs is spatially coincident with a stream/plume of stars previouslyidentified. We find that the photometric colours of the stream GCs match thoseassociated with NGC 4342, and that the recession velocity of the combined GCsfrom the stream and NGC 4342 match the recession velocity for NGC 4342 itself.These results suggest that NGC 4342 is being stripped of GCs (and stars) as itundergoes a tidal interaction with the nearby elliptical galaxy NGC 4365. Wecompare NGC 4342 to two well-known, tidally stripped galaxies (M32 and NGC4486B) and find various similarities. We also discuss previous claims by Bogdanet al. (2012a) that NGC 4342 cannot be undergoing significant tidal strippingbecause it hosts a large dark matter halo.
