This turns out to be a sequel to Isvik, which I thought was overlong and with a weak and unbelievable plot.

It is Boys' Own Paper , read down the middle of the page stuff , which by and large would insult the intelligence of a 9 year old , and not worth wasting your time on, even in this peculiar post-coronavirus world we live in
