Specific Reid fic

A whole ago I read a story in which Reid was kidnapped and held in a basement I think. I seem to recall that the unsub went on to kidnap his wife and son and put them in the basement with Reid. I can also remember the wife and son then being put in a house fire where the wife died and the unsub went onto kill his son in the hospital before going after reid who was also in hospital.
confusing I know but I feel like I've been searching forever to no reward. I don't know whether I've completely imagined it or just pieced together numerous stories. Any help would he greatly appreciated, thankyou!
