He was busy trying to solve a sixty foot, sixty ton problem: a sperm whale that refused to give up. The harpoon had not found the vital spotthe gunner blamed the choppy sea for spoiling his aimand now the whale was towing the 110 ton boat behind it. Even with the engine reversed, the craft kept moving forward. The gunner got ready to fire a second harpoon. In the bloodstained water the mammoth beast continued its agonising struggle. He was a mature male, a bull. His slateblue body bore scars, souvenirs of epic battles with giant squid he had hunted in the dark depths. The biggest of these pink monsters, whose humanlike eyes were more than fifteen inches across, weighed 42 tons and measured 66 feet. But even the ir powerful beaks and ten suc kered tentacles were no match for the whale39。 only the older ones understood that this was no celebration. For several nights to e there would be plenty of bodies to feed the flames. Niy miles inland, nothing broke the forest hush. A full moon silvered the treetops and light leaked down to the snowcovered floor beneath. Scraps of mist seemed caught on prickly branches. From the shadows, a ghostly shape glided into a clearing. Tw o amber eyes searched the dappled darkness. Stealthily the wolf a dvanced. Hunger had driven h im from his snug den. He knew where to find a good meal. Not the mice and birds he had lived on lately, but a hare he had killed and buried in the frozen ground to keep it fresh and safe from crows and ravens. As the dogwolf wound through the trees at an effortless lope, which could carry him as far as 120 miles in a single day, his thic k browngrey yellow fur gleamed in the moonlight. He was a fine big dog:owdered horn cured colds, measles, nosebleeds, vomiting, heart weakness. The Japanese claimed it fought fever. Certain people even swore by it as a love potion. Most poachers are poor. So the temptation to earn money by any means, however risky, is very strong.
