Complete story — includes the ending
Ned is with a girl in her college dorm when a haunting occurs, and he calls Melinda. It is soon discovered that the hauntings are connected to a chain email about 'Sally Stitch'. The ghost thinks that her decision not to forward it was what caused the car accident that left her mother in a coma, and is terrorizing people to make sure they forward it, thinking that will save her mother, but her mother is sicker than she knew. A little girl who has terminal cancer and lives in the hospital turns out to be the creator of the email.
