Unit 3 OLD TOM TH E KILLER WH ALE I was 16 when I began work i n June1902 at the whali ng stati on. I had heard of the kil l ers that every year hel ped whal ers catch huge whal es. I thought, at the ti m e, that this was just a story but then I wi tnessed i t wi th m y won eyes m any tim es. O n the afternoon I arri ved at the stati on, as I was sorti ng out m y acm odati on, I heard a l oud noise i ng from the bay. We ran down to the shore i n ti m e to see an enorm ous anim al opposi te us throwi ng itsel f out of the water and then crashi ng down agai n. It was bl ack and whi te and fi shshaped. But I knew i t wasn’t a fi sh. “That’s O l d Tom, the kil l er, ” one of the whal ers. Gee, cal l ed out to m e. “He’s tel i ng us there’s a whal e out there for us. ” Another whal er yel ed out, “Rushoo…rushoo. ” Thi s was the cal that announced there was about to be a whal e hunt. “Com e on, Cl ancy. To the boat, ” Gee sai d as he ran ahead of m e. I had al ready heard that Gee di dn’t li ke bei ng kept waiti ng, so even though I di dn’t have the ri ght clothes on, I raced after hi m. Wi thout pausing we jum ped i nto the boat with the other whal ers and headed out i nto the bay. I l ooked down i nto the water and coul d see O l d Tom swimm ing by the boat, showi ng us the way. A few mi nutes l ater, there was no Tom , so Gee started beati ng the water with hi s oar and there was Tom , ci rcli ng back to the boat, l eadi ng us to the hunt agai n. Usi ng a tel escope we coul d see that som ethi ng was happening. As we drew cl oser, I coul d see a whal e bei ng atacked by a pack of about si x other kil l ers. “What’re they doi ng?” I asked Gee. “Wel l, i t’s team work the kil l ers over there are throwi ng themselves on top of the whal e’s bl owhol e to stop it breathi ng. And those others are stopping i t divi ng or fleei ng out to sea,” Gee tol d me, pointi ng towards the hunt. And just at that m om ent, the m ost extraordinary thing happened. The ki l ers started raci ng between our boat and the shal e just li ke a pack of exci ted dogs. Then the harpoon was ready and the man i n the bow of the boat ai med i t at the whal e. He l et it go and the harpoon hit the spot. Bei ng badly wounded, the whal e soon died. Withi n a m om ent or two, its body was dragged swi ftly by the kil lers down into the depths of the sea. The men started turning the boat around to go home. “What’s happened?” I asked. “Have we l ost the whale?” “Oh no, ” Jack repli ed. “We’l return tomorrow to bring in the body.

H is nam e was Tony and he seem ed m ore l i ke a hum an than a m achi ne. H e was tal and handsom e with sm ooth hai r and a deep voi ce al though hi s faci al expression never changed. O n the second morning Tony, weari ng an apron, brought her breakfast and then asked her whether she needed hel p dresi ng. She fel t em barrassed and qui ckly tol d him to go. It was di sturbi ng and fri ghteni ng that he l ooked so hum an. O ne day, Cl ai re m enti oned that she di dn’t think she was clever. Tony sai d that she m ust fel very unhappy to say that. Cl ai re thought i t was ri di cul ous to be offered sym pathy by a robot. But she began to trust him. She tol d hi m how she was overwei ght and thi s m ade her feel unhappy. Al so she fel t her hom e wasn’t el egant enough for som eone l i ke Larry who wanted to im prove hi s social posi ti on. She wasn’t l i ke Gl adys Cl affern, one of the ri chest and m ost powerful wom en around. As a favor Tony prom i sed to help Cl aire m ake hersel f smarter and her hom e m ore el egant. So Cl ai re borrowed a pi l e of books from the l i brary for him to read, or rather, scan. She l ooked at hi s fi ngers wi th wonder as they turned each page and suddenl y reached for hi s hand. She was am azed by hi s fi ngernai l s and the softness and warm th of hi s ski n. H ow absurd, she thought. H e was just a machi ne. Tony gave Cl ai re a new haircut and changed the m akeup she wore. As he was not al lowed to ac pany her to the shops, he wrote out a li st of i tem s for her. Cl aire went into the ci ty and bought curtai ns, cushi ons, a carpet and beddi ng. Then she went i nto a jewel ry shop to buy a neckl ace. When the cl erk at the counter was rude to her, she rang Tony up and tol d the cl erk to speak to him . The cl erk imm ediatel y changed hi s atti tude. Cl aire thanked Tony, tel li ng him that he was a “dear”. As she turned around, there stood Gl adys Cl affern. H ow awful to be di scovered by her, Clai re thought. By the am used and surprised l ook on her face, Cl ai re knew that Gl adys thought she was havi ng an affai r. After al l, she knew Cl ai re’s husband’s nam e was Lary, not Tony.
