This was a good story. I've been meaning to check out Rose's work for some time and felt starting with a short story would work best with my schedule, at the moment.
I was pleased with this. I enjoyed the mystery that the somewhat cliff-hanger ending left. There are a few possibilities for the source of the incessant tap, tap, tapping. I can't choose just one that I'd like to see as the cause.
As a first venture into Rose's work, I feel it was a good move on my part. I won't hesitate to read more in the future.
