10: Death in the Chat Room (William Melchert)

On a cold Sunday in March 2008, an 18-year-old woman jumps off a bridge in Canada's capital, Ottawa. She sinks into the icy water and welcomes death to end the darkness that has consumed her mind. Three years before, a 32-year-old man hanged himself in his apartment in the city of Coventry in central England. He could see no other way out. The two apparently have nothing in common, but they both leave behind an open computer. It turns out that they have been active on the same online suicide forum. And they have been talking to the same person.

From Podimo and Vespucci — this is The Darkness Vaults.
