My ultimate ambition is to introduce a captive pack of wolves into the wild and live with them. - Shaun Ellis

I knew that scent was important and I discovered that if I put on different clothes or washed or at different food, the beta male would start nipping me again until he was satisfied that the new smell didn't mean I was going to react differently to his approach or that my mood had changed. The other high-ranking wolves did the same thing, but it didn't involve every wolf in the enclosure. The lower-ranking members of the pack, I was to learn, don't question what the higher-ranking members decide; they are foot soldiers - they have an important job to do, but it is not to think for themselves.

I had always aimed to bridge the gap between humans and wolves but being able to speak for the wolf is pointless unless you can communicate with the people who need to hear you. What Helen couldn't cope with was my inability to give myself completely. Of the two worlds I lived in, one was devoid of emotion, the other was full of it. I knew I turned my emotions off when I was in the wolf world but I had always thought I turned them back on when I walked up the track to the caravan. I never did; I never truly left the forest.

I've seen three wolves successfully take on a seven-hundred- to eight-hundred-pound bear and remain in control throughout just by waiting until it was pitch dark for the final assault. Being nocturnal animals, the wolves could still see clearly, but the bear, which is fundamentally a daytime creature, was at a disadvantage.
