Of course the king is most concerned with Hamlet’s location. He’s probably worried about him popping out behind an arras at any moment. Is he hiding in a cabinet? The broom cupboard? Check under the bed before you go to sleep.
You could be eating breakfast – and BLAM – he comes out from under the tablecloth. There could be a Hamlet hiding in the garden, behind a tree during an afternoon walk – or a Hamlet under the stairs – or a Hamlet rolled up in a rug like Cleopatra delivered to her lover. There could be a Hamlet in the basement, a Hamlet in the throne room, a Hamlet in the hall.
He could be anywhere.
