Now with Colonel Roosevelt, the magnum opus is complete. And it deserves to stand as the definitive study of its restless, mutable, ever-boyish, erudite and tirelessly energetic subject. Mr. Morris has addressed the toughest and most frustrating part of Roosevelt’s life with the same care and precision that he brought to the two earlier installments. And if this story of a lifetime is his own life’s work, he has reason to be immensely proud. -- Janet Maslin -- NY Times.
