Pursuit - Pursuit and the Man Who Died Late

After returning from a wedding, Inspector Peter Black is looking through his messages. There is one from Dr. Bishop, whom would like to speak with him. The Inspector calls him on the telephone. Bishop asks "Would you mind coming down for a moment? I've got something terribly interesting to show you". Inspector says "Oh well, I'm taking a holiday today, my brother's wedding". Bishop says "I see, how nice, all sorts of congratulations. He's the Army chap, isn't he?" Inspector says "Navy". Bishop says "Of course, but I do wish you'd pop in for a moment, I'm so afraid someone else will get it and it's your sort of thing". Inspector says "Is it alive or dead? Bishop says "Dead, amazingly dead, I've never seen anything like it you must see it's the best one I've had for ages". Later, on his way home, the Inspector stopped by to see Dr. Bishop. He says "Hello Inspector, so glad you could come. I don't mind telling you this is a red letter day for me. Oh, I've got him in the examination room". Inspector says "Oh really, I suppose the fact that he's dead helps". Bishop says "Rather does. Wait till I tell the chaps at the RCP. Now, have a look at this!"
