I have immensely enjoyed writing the series, but every voyage has its ending and Drinkwater exceeded his allotted three score years and ten to die not ignobly. To those of my readers who have shared something of this enjoyment, may I simply express my gratitude. Your support meant the whole tale could be told, and while your precise image of Nathaniel Drinkwater may differ slightly from my own, the substance of his invention is common to us both.
