Door Bell Saga Continues

A few months ago, Derek installed a new door bell.  After a few glitches, it appeared to be working.  Imagine my surprise then, when some repeat customers reported at breakfast this morning, how check-ins went yesterday!

While I was out, a number of guests arrived shortly before 4:00 p.m. (check-in time) and rang the doorbell.
Nothing...So, they decided to go out into the garden and enjoy the wonderful weather we've been experiencing.  Then, some returning guests arrived and as they knew the door code, let themselves and the newly-arriving guests into the house.  Since Basil (aka Derek) was not coming to the door, everyone installed themselves in the Fireplace Lounge for a good chin wag.

A few minutes later, the phone rang and the son of the returning guests asked for his mother (who was to have shown up by 4:00 p.m.).  By this time,  Basil (aka Derek) could hear the laughter and chatter in the Lounge and went running upstairs to discover a room full of guests he had not heard at the door!
Needless to say, I had to hear this from the guests. Derek, like Basil, would hate to admit anything like that to Sybil......

I've checked the doorbell myself - whatever the problem was, it has now gone away.....thank goodness!
