Sleep last night was punctuated by a slow peeping. It was not constant and in the dark I could find no evidence of where it was coming from. This morning all has been revealed. It was a small dish washer under the sink !!!! What ever next! The maid had put our small collection of cups and plates in the machine. The blasted bleeping was not heard by David who of course does not wear his hearing aid in bed! Never mind. The sun is out now!
