Since LM Montgomery is just the best author in the world, no surprise that these short stories were good. True, I like her other short stories from Chronicles or Blythe are quoted much more, but these stories were mainly nice because the characters were all kindred spirits.
My favorite one may be the last one, The Strike at Putney. It was humorous and the women were all sensible and intelligent and didn't the men get what they deserved XD
I am pretty sure A Case of Trespass is in another book, because I've read this one before.
