Five years ago, Rosa walked to the end of the pier in the dead of night. She looked into the swirling water, and jumped. She was a brilliant young Cambridge student who had just lost her father. Her death was tragic, but not unexpected.

Find me, Jar. Find me, before they do…

Is Rosa really dead? And, if she is, who is playing games with the ones she left behind?
