  Hints of lepton flavor violation have been observed by LHCb in the rate of
the decay $B\to K\mu^+\mu^-$ relative to that of $B\to K e^+e^-$. This can be
explained by new scalars and fermions which couple to standard model particles
and contribute to these processes at loop level. We explore a simple model of
this kind, in which one of the new fermions is a dark matter candidate, while
the other is a heavy vector-like quark and the scalar is an inert Higgs
doublet. We explore the constraints on this model from flavor observables, dark
matter direct detection, and LHC run II searches, and find that, while
currently viable, this scenario will be directly tested by future results from
all three probes.
