I am certain I have the sequence of notes correct, but the main ghost won’t die. If the secondary ghosts are numbered 1 - 5 from the left to right as you look at the tomb, then the sequence is 3, 5, 2 then 1. Please help!
OK - Just realized I have to play the notes in reverse. Arrrggh! Sometimes I wonder why I do this for fun . . . .
