Thomas MacMillan is 40, an orphan, an heir, a laboratory technician, an autodidact of esoteric intellectual appetites, as he writes this interrogation of the past disguised as a letter to his absent lover. Like Andre Alexis, both Thomas's restlessly sexual mother, Katarina, and his courtly mentor, Henry Wing, were born in Trinidad and resettled in Canada. Their unconventional lifelong relationship is both the deepest mystery and the central fact of Thomas's life, the creature in the center of his heart and the heart of this fictional memoir, the beast he walks around and around, prods with questions and tries to fix with lists of explanations and attributes.
