Query: Mistake

The book is a mistake. The Penge Bungalow Murders have been made legendary in the Rumpole universe. The problem is the case, and Rumpole's handling of it is absolutely ordinary. There is no reason that this should be his proudest moment. It follows the structure of many of Rumpole's cases. Incompetent leader, Rumpole helps muscle him of the case and takes it himself. The view of a young Rumpole is delightful, although the description in another Rumpole story of himself then as a young barrister he is not at all sure he would like doesn't seem to apply. It would have been a fined thing to see a young Rumpole, but the Penge Bungalow Murders should have been left out. It is like when a friend talks up a movie as the greatest thing he's ever seen for years, and when you see it...... it is just ordinary.
