Blind Spot Although Geoffrey Blake and his sister Katherine have unusual abilities and Maggie Wren is a reasonably capable heroine, I didn't enjoy the last story quite as much as the first three in Must Love Hellhounds. Sir Pup is the hellhound in this offering and my favorite part of the story. In fact, Sir Pup had the largest role, the most engaging personality, and quite probably the scariest displays of power in the collection. ( )
