Edmund Russell examines interactions between greyhounds and their owners in England from 1200 to 1900 to prove that history is an evolutionary process.

The letters contained within the book were written during a journey through Canada and the United States, taken by the author's father, mother, and brother William, during the autumn of the previous year. While at first these letters were meant for private correspondence, the author has managed to convince the parents to publish them. For these letters, according to the author, will be able to give a better way of introducing the people of America to a British audience, and it is hoped that the perspectives and experiences offered by these letters will provide a different view of the country.
