From the Chaosium website:
Three Adventures for Call of Cthulhu
This monograph is the result of our second Chaosium.com Call of Cthulhu Adventure Contest. Three submissions were chosen this time around.
'War of the Spectres' is a modern-day scenario reflecting the events of the day. Likewise, 'The Glendale Faeries' is set in the modern-day, set in a quiet Cumbrian village. Finally, 'Madness of the Black Opal' is set in the 1920s and concerns a small Australian city on the southern coast named Adelaide.
We hope your investigators survive these Strange Tales of Dread and Wonder.
