I don't believe anyone can go through the prison experience without being changed by it. The experience becomes part of your identity forever.

I can say now is that sneaking up on people is a major delight in my old age, but it always has been. A desire, even a need, to shock.

We humans are in such a strange position—we are still animals whose behavior reflects that of our ancestors, yet we are unique—unlike any other animal on earth. Our distinctiveness separates us and makes it easy to forget where we came from. Perhaps dogs help us remember the depth of our roots, reminding us—the animals at the other end of the leash—that we may be special, but we are not alone. No wonder we call them our best friends.

I felt compelled to blow the whistle on the penal system, under the delusion that doing so might result in some change, or at least save a few women from the same fate. Eternally naïve, that's me.

Although I was simply what today would be called a "mule" - the bottom of the food chain in the drug biz - the federal system treated me from beginning to end like a major criminal, and I still don't know why, other than that in those days, 6.5 ounces of heroin was a big load. Ludicrous by today's standards, when coke, heroin, and weed are shipped across the border by the ton.

There's a stone I had made for Luke at the top of the hill road, where the pasture opens wide and the setting sun highlights the words carved into its face. "That'll do, Luke, that'll do." The words are said to working dogs all over the world when the chores are done and the flock is settled: "That'll do dog, come home now, your work is done." Luke's work is done too. He took my heart and ran with it, and he's running still, fast and strong, a piece of my heart bound up with his, forever.

I was addicted to amphetamines at the time I got busted, but I tend to think I was on a determined, self-destruct course that had little to do with the effect of Benzedrine.
