The Ghosts of London

From the publisher: Starting on August 31, a ghost on Durward Street appears every day at 3:40 AM and remains until it has tasted blood. Another starts appearing on Hanbury Street on September 8. Can you put them to rest before the body count reaches a point that the supernatural aspect of the killings can no longer be ignored? An adventure designed for mid/high-level characters set in the Fellowship of the White Star setting of Earth, 1908.
