An IntercontinuityCrossover between SherlockHolmes and the CthulhuMythos, "Quiet Desperation" was inspired by Creator/NeilGaiman's "A Study in Emerald" and tells the other side of that story.

Dr. Watson has found himself trapped in a mind-fraying hell. After a terrifying ordeal in Afghanistan, he was honourably discharged from service as a surgeon in Albion's army, only to be assigned as a physician for a member of Albion's Royal family. But just as he is on the brink of despair, he is found by a man who offers him hope for salvation - not only for himself, but perhaps all of humanity. A man named SherlockHolmes.

"Quiet Desperation" is currently a work in progress, and can be found [[ here]].
