Martha, it turned out, had suspected something rotten for a long time herself.

She had simply never had anyone to tell.

I think about Martha more than she will ever know.

For twenty years she had been the woman in the background of my family — the one who kept the house running, thanked at holidays and otherwise unseen, who knew where everything was and was asked about nothing.

And it was Martha, in the end, invisible Martha, who had the eyes to see what a boardroom full of clever men had missed, and the spine to act on it, and the patience to do it right.

She had watched Callum move through our house for three years wearing his devoted-husband face, and something in her, some old servant’s instinct honed over decades of watching people who thought themselves unwatched, had refused to buy it.
