Before the lamps were lit, shadows came

teeming forth from every corner. But behind

the desk, something else was there.

Dark. Malicious. Waiting.

Just as evidence starts falling into place, Scrooge is yet again visited by the ghost of Jacob Marley, only this time Marley is not alone. The trio are faced with murder, kidnappings, and a pack of half-men, half dogs before eventually discovering an underground scheme as wicked as the force that haunts them. Now they must work together to find the thread that binds these crimes together, stop the criminals, and squelch the dark malevolence that threatens to take over the city and end them all.
