When they asked some old Roman philosopher or other how he wanted to die, he said he would open his veins in a warm bath. I thought it would be easy, lying in the tub and seeing the redness flower from my wrists, flush after flush through the clear water, till I sank to sleep under a surface gaudy as poppies. But when it came right down to it, the skin of my wrist looked so white and defenseless that I couldn't do it. It was as if what I wanted to kill wasn't in that skin or the thin blue pulse that jumped under my thumb, but somewhere else, deeper, more secret, and a whole lot harder to get at.
