Then Beatrice Pymm died.

First stop, ten minutes later, the bank of the River Orwell, the same spot where Beatrice Pymm had been painting that day. The killer left the van's engine running and climbed out. She walked to the passenger side of the van, opened the door, and removed the easel, the canvas, and the rucksack.

The easel was erected very near the slow-moving water, the canvas placed on it. The killer opened the rucksack, removed the paints and palette, and laid them on the damp ground. She glanced at the unfinished painting and thought it was rather good. A shame she couldn't have killed someone with less talent.

Next, she removed the half-empty bottle of claret, poured the remainder of the wine into the river, and dropped the bottle at the legs of the easel. Poor Beatrice. Too much wine, a careless step, a plunge into frigid water, a slow journey to the open sea.

Cause of death: presumed drowned, presumed accidental.

Case closed.

Six hours later, the van passed through the West Midlands village of Whitchurch and turned onto a rough track skirting the edge of a barley field. The grave had been dug the previous night-deep enough to conceal a corpse but not so deep that it might never be found.

She dragged Beatrice Pymm's body from the back of the van and stripped away the bloody clothing. She took hold of the naked corpse by the feet and dragged it closer to the grave. Then the killer walked back to the van and removed three items: an iron mallet, a red brick, and a small spade.

This was the part she dreaded most, for some reason worse than the murder itself. She dropped the three items next to the body and steadied herself. Fighting off another wave of nausea she took the mallet in her gloved hand, raised it, and crushed Beatrice Pymm's nose.
