Publisher Blurb: A madman feeds the birds, paranoid they are watching him. Scientists find their experiments ruined, when the same birds stare from the rooftops. And, when a biologist dissects one of the birds, there is something terrifying inside. Written by Graham Walmsley, the author of The Dying of St Margaret's, The Watchers In The Sky is a Purist adventure for Trail of Cthulhu. There is no glory in fighting the Mythos, only madness and despair. Your friends cannot be trusted, your knowledge means nothing, and everything you hold dear turns to dust. The more you discover, the more the Mythos infects your mind, and the minds of those you love.
