Fetch, My boy! (S2E13)

GM Notes:
Several people have turned up dead in the last few days. The last two of these were killed in locked rooms, which were locked from the inside. Dr. VanLocklear was first, followed by two first-year co-eds: Valerie Jones and Salai Mumbai. Then came the death of Joseph Mumbai, an usher at the Broadway Theatre. They show the same cause of death in all cases: Hair all of white, and heart failure. In all cases, there are reflective surfaces nearby. Three of the victims had purchases at the Broadway Theatre on their banking history, on Friday, September 19. Broadway was showing a movie called 'The Beyond (1981)'.

Two Fetches are on the loose, and feeding very well indeed. One major Fetch, and one minor.
