Missing Heroine

I worked on my novel for longer than usual. Afterwards something niggled at the back of my mind while I collected a prescription from the doctor's surgery, had it filled in at the chemist and then withdrew some money from the bank. I hurried home to greet son number two whose birthday is today. Off we went to my favourite vegetarian restaurant, Sakonis, in Harrow. As usual the food was delicious. While enjoying both the meal and my son's company, I realised what was wrong the part I wrote this morning. The hero attends a dinner at his parents' house to which, I realised, the heroine should have been invited. Tomorrow, much to her relief and my own she will be there.
