Playing Sudoku in the interval

Dear Heart,
I am all at sea. Libby had an army of friends in the audience who offered rapturous applause during the curtain call and left this bouquet of beautiful flowers outside the dressing room. Accompanying it was a card with a photograph of a weird nun looking at inappropriate pictures of priests on the interweb. Needless to say, it caused me a great deal of discomfort, fear and embarrassment.
Love, Lydia x
