There are many connections between the properties of globular cluster systems and those of thegalaxies that host them, making them useful tracers of the evolutionary history of early-type galaxies. Mergers and accretion events may alter the spatial distribution of the system, as well as their colours. We present a study of the globular cluster system of the elliptical galaxy NGC 3640, using observations from GMOS/Gemini. In our analysis, we find evidence of an interaction between NGC 3640 and its companion, NGC 3641, in the form of an apparent trail of globular clusters between the two galaxies.
