The Falmouth-bound coach hesitated at the brow of a low hill, its wheels jerking and spinning against yet another ridge of frozen mud. The horses, four-in-hand, took the strain, stamping with frustration, their breath steaming in the pale, misty sunlight. They, more than any, were aware that their part of the journey was almost over.

It was February and still bitterly cold, as it had been since this year of 1818 had first dawned. Longer than that, many would say along Cornwall's southern approaches. Trees like black bones, as if they would never throw a leaf or bud again; slate walls and the occasional farm roof like polished metal.

The coachman, big and shapeless in his heavily caped coat, flicked the reins. No urgency, no haste; he knew his horses and the road as he knew his own strength. His passengers and baggage took second place.

At the rear of the coach, the guard, equally unrecognizable under layers of clothing and an old blanket, wiped his eyes and stared across the straining horses and saw a flock of gulls rise from somewhere, circling, perhaps looking for food as the vehicle rolled past. The sea was never far away. The horses were changed at the authorized stables, but he and the driver had been with the coach all the way from Plymouth. He shifted his buttocks to restore the circulation to his limbs and felt the pressure of his gun beneath the blanket. The coach carried mail as well as passengers, and the crest emblazoned on either door proclaimed risk as well as pride.
