I am certain that Fred and George would quite naturally have frequently   
   checked up on their BROTHER Ron on the Map, and thus seen Peter Pettigrew on   
   the map!  The scares caused by the petrification epidemic (Chamber of Secrets)   
   and Sirius Black would    
   surely have caused Fred and George to check up on their brother!    
      
   When it was announced that Ginny had been taken down into the Chamber of   
   Secrets, why didn't Fred and George whip out their map to look for her?
