My mother’s main aim in life was to get from the cradle to the grave with the minimum of fuss and bother and the maximum of tea and Battenberg. Along the way she brought up three children, attended a lot of Women’s Federation meetings and managed to squeeze a few severely burned meals somewhere in between. It wasn’t until I was six that I realized that cake wasn’t meant to be 87 percent carbon and that chicken actually tasted of something. Despite all this, or perhaps even because of it, we all loved her a great deal.

M y mother lived less than a mile away and actually on the route to work, so I often dropped in just to make sure she was okay and wasn’t about to embark on some harebrained scheme, as was her habit. A few years ago she had hoarded tinned pears on the principle that once she’d cornered the market, she could “name her price,” a flagrant misunderstanding of the rules of supply and demand that did no damage to the tinned-fruit producers of the world but condemned her immediate family and friends to pears at every meal for almost three years.

She was the sort of parent you would want to have living close by, but only on the grounds that she would then never come to stay. I loved her dearly, but in small doses. A cup of tea here, a dinner there—and as much child care as I could squeeze out of her. The text excuse I gave Landen was actually something of a mild fib, as the real reason for my popping around was to pick something up from Mycroft’s workshop.

“Hello, darling!” said Mum as soon as she opened the door. “Did you get my text?”

“Yes. But you must learn how to use the backspace and delete keys—it all came out as nonsense.”

“‘L&Ks4DnRNXT-SNDY??’” she repeated, showing me her cell phone. “What else could that mean but ‘Landen and kids for dinner next Sunday?’ Really, darling, how you even begin to communicate with your children, I have no idea.”

“That wasn’t real text shorthand,” I said, narrowing my eyes suspiciously. “You just made it up.”

“I’m barely eighty-two,” she said indignantly. “I’m not on the scrap heap yet. Made up the text indeed! Do you want to come back for lunch?” she added, without seeming to draw breath. “I’ve got a few friends coming around, and after we’ve discussed who is the most unwell, we’ll agree volubly with one another about the sorry state of the nation and then put it all to rights with poorly thought-out and totally impractical ideas. And if there’s time after that, we might even play cribbage.”
