Possible delay in Quoth the Raven

I'm trying to post chapters on Mondays and Thursdays.
At noon tomorrow I'm going to have a total left knee replacement. I'm not worried about it since I had the right knee replaced 15 years ago (the 9th surgery on that knee over 30 years) so I'm not unduly concerned about this surgery. I've lived alone since my wife passed away, but I had the fixed the house for handicap accessibility since she was virtually bedridden for 9 years. So now the house is set up fro easy movement and the refrigerator is well stocked. I expect to be released and home Thursday afternoon.
I'm not sure if I'll be able to post the next that night but I will get it up as soon as possible.
