Dear NAME
When I called at [your office] yesterday I was very sorry to learn that you had been in a car accident on your way home from work recently. However, I was equally relieved to learn that you are making good progress and are likely to be back at work again in a few weeks.
I wish you a speedy recovery.
Yours sincerely,
