  We demonstrate coherent control over the photoelectron circular dichroism in
randomly oriented chiral molecules, based on quantum interference between
multiple photoionization pathways. To significantly enhance the chiral
signature, we use a finite manifold of indistinguishable $(1+1^\prime)$ REMPI
pathways interfering at a common photoelectron energy but probing different
intermediate states. We show that this coherent control mechanism maximizes the
number of molecular states that constructively contribute to the dichroism at
an optimal photoelectron energy and thus outperforms other schemes, including
interference between opposite-parity pathways driven by bichromatic $({\omega},
2{\omega})$ fields as well as sequential pump-probe ionization.
