Pointer had almost sent him packing. But something about the quietly spoken, polite but determined Mexican made him stop and listen. Herman explained that he was a good gardener, had trained as a mechanic in Mexico, was hardworking and trustworthy.

Pointer believed him, and he remembered the Pointer family motto: initiative and determination. He took him on, part-time at first, but Herman soon made himself indispensable. For the first five years he travelled in every day from his tenement room in New York. Occasionally, when there was a lot to do, he would stay over in the small separate annexe.

Eventually he just moved in. For good. Not just because he had become a loyal and trusted member of the Pointer household, but also because he'd become a firm friend and favourite of young Chuck.

He was now one of the family. He had no family of his own – or none that he had ever mentioned – and he treated Chuck as if he were his own son. At Chuck's memorial service Pointer and Herman had stood side by side, weeping silently.

Now they met when it was necessary. Pointer would summon him by mobile and Herman would use his key to the back door of the darkened house. Then he would wait until his master emerged from the gloom. They would discuss what was necessary, what was required, and then go back to their separate tasks. They never spoke about Chuck; there was nothing more they could say.

From the outside, the house and grounds looked just as they always had. Neat, tidy, well-clipped hedges, fir trees and trimmed lawns.

Inside, it was totally different. Changed completely, like its owner. Most of the rooms were no longer used; they simply gathered dust behind closed curtains and fixed shutters. The few rooms Pointer inhabited in the eastern wing of the grand building never saw daylight. The decorative chandeliers were never switched on. Pointer moved around and operated in nothing more than the light from a single small lamp. Darkness had enveloped his soul. His world was darkness too.
