  We present a wide-field study of the globular cluster systems (GCS) of the
elliptical galaxy NGC 3640 and its companion NGC 3641, based on observations
from Gemini Multi-Object Spectrograph/Gemini. NGC 3640 is a shell galaxy which
presents a complex morphology, which previous studies have indicated as the
sign of a recent 'dry' merger, although whether its nearest neighbour could
have influenced these substructures remains an open question. In this work, we
trace the spatial distribution of the globular clusters (GCs) as well as their
colour distribution, finding a potential bridge of red GCs that connects NGC
3640 to its less massive companion, and signs that the blue GCs were spatially
disturbed by the event that created the shells.
