Each month, on the 1st of the month, the #pinchpunchpost twitter group posts a picture of a prescribed animal. This month's animal is The Whale. Very rapidly, however, Captain Ahab came to dominate my image; his dark presence and brooding obsession informed the basis of the composition. His nemesis, Moby Dick, appears only at the very end of the immense novel. Much like Rebecca, the book is named after a character who is only referred to and not seen. In keeping with this, the whale images are barely visible, carved onto the shaft of the harpoon.
