This is quite a nice little short story, mainly focused around Leon's background, including some stuff that I had forgotten from the earlier Chronicles of St Mary's books.
In recent short stories, I feel that Jodi has been stepping away from the action packed craziness, and going slightly more in the background of the characters, or rehashing the events after they have happened (much like "And Now For Something Completely Different", which centers around landing on Mars). This is definitely one of those, as Leon thinks about his earlier life, his first marriage and children, his mum and his first meeting with Max.
Max doesn't really play a big part in this story, she appears towards the end, but as you may have guessed from the title, it deals with Max's father, and him coming back into her life unexpectedly. Thankfully, all of St Mary's rallies around Max, with some quite inventive ways to get him back out of her life again, and the briefest mentions of Clive Ronan.
With the release of "Doing Time", a new series based around the Time Police frequently mentioned in the St Mary's books, I wonder if Jodi will still have enough time to dedicate to the St Mary's series. We are quite spoilt, with regular releases and regular short stories to keep us engaged. It is a really good series, and I just hope it doesn't start going downhill, if she spreads herself too thin.
