angry Martians. He sees Mullet and Finch again, however, and tries to escape in a hijacked airship. He loses control of the airship and finds himself in a conservatory with a harp, which shrinks to the size of his palm. Mullet and Finch confront him, demanding that he give them the harp, but he refuses and appears again on the airship, which is hurtling toward the ground. Transported to yet another world, he is rescued from a frozen river by a group of Neanderthals, and a voice comes from the harp, telling him that friends will search for him on the river.

Finally, van Bleeck is brutally assaulted and dies after leaving Renie and !Xabbu with three names: Martine Desroubins, Blue Dog Anchorite, and Bolivar Atasco. The first two are hackers that agree to
