So then, in default of the true beginning, let us commence with the character and environment of Maxwell Cheyne, following on with the strange episode which took place in the Edgecombe Hotel in Plymouth, and from which started that extraordinary series of events which I have called The Cheyne Mystery.

Maxwell Cheyne was born in 1891, so that when his adventure began in the month of March, 1920, he was just twenty-nine. His father was a navy man, commander of one of His Majesty’s smaller cruisers, and from him the boy presumably inherited his intense love of the sea and of adventure. Captain Cheyne had Irish blood in his veins and exhibited some of the characteristics of that irritating though lovable race. He was a man of brilliant attainments, resourceful, dashing, spirited and, moreover, a fine seaman, but a certain impetuosity, amounting at times to recklessness, just prevented his attaining the highest rank in his profession. In character he was as straight as a die, and kindly, generous, and openhanded to a fault, but he was improvident and inclined to live too much in the present. And these characteristics were destined to affect his son’s life, not only directly through heredity, but indirectly through environment also.

When Maxwell was nine his father died suddenly, and then it was found that the commander had been living up to his income and had made but scant provision for his widow and son and daughter. Dreams of Harrow and Cambridge had to be abandoned and, instead, the boy was educated at the local grammar school, and then entered the office of a Fenchurch Street shipping firm as junior clerk.

In his twentieth year the family fortunes were again reversed. His mother came in for a legacy from an uncle, a sheep farmer in Australia. It was not a fortune, but it meant a fairly substantial competence. Mrs. Cheyne bought back Warren Lodge, their old home, a small Georgian house standing in pleasant grounds on the estuary of the Dart. Maxwell thereupon threw up his job at the shipping office, followed his mother to Devonshire, and settled down to the leisurely life of a country gentleman. Among other hobbies he dabbled spasmodically in literature, producing a couple of novels, one of which was published and sold with fair success.

But the sea was in his blood. He bought a yacht, and with the help of the gardener’s son, Dan, sailed her in fair weather and foul, thereby gaining skill and judgment in things nautical, as well as a first-hand knowledge of the shores and tides and currents of the western portion of the English Channel.

Thus it came to pass that when, three years after the return to Devon, the war broke out, he volunteered for the navy and was at once accepted. There he served with enthusiasm if not with distinction, gaining very much the reputation which his father had held before him. During the intensive submarine campaign he was wounded in an action with a U-boat, which resulted in his being invalided out of the service. On demobilization he returned home and took up his former pursuits of yachting, literature, and generally having as slack and easy a time as his energetic nature would allow. Some eighteen months passed, and then occurred the incident which might be said definitely to begin his Adventure.

One damp and bleak March day Cheyne set out for Plymouth from Warren Lodge, his home on the estuary of the Dart. He wished to make a number of small purchases, and his mother and sister had entrusted him with commissions. Also he desired to consult his banker as to some question of investments. With a full program before him he pulled on his oilskins, and having assured his mother he would be back in time for dinner, he mounted his motor bicycle and rode off.

In due course he reached Plymouth, left his machine at a garage, and set about his business. About one o’clock he gravitated towards the Edgecombe Hotel, where after a cocktail he sat down in the lounge to rest for a few minutes before lunch.

He was looking idly over The Times when the voice of a page broke in on his thoughts.

“Gentleman to see you, sir.”
