Trowbridge's garden tour: Macbeth
Mid-crisis, the prime minister stops to show Kate a tree. He says a Winfield House groundskeeper planted a cutting of the Birnam Oak because Barbara Hutton loved the Scottish play. The real Birnam Oak still stands by the River Tay in Perthshire, billed as the last survivor of the wood that marched on Dunsinane. Trowbridge quotes the prophecy about a king who can't lose until the trees start walking, and doesn't see himself in it at all.
