There's something about this whole business - that has been tickling my brainbox. - What is it? On the night of the robbery, when young Mr Brown called out, the thief took to his heels and ran down the stairs. Came straight through the shop and out the front door, setting off the alarm. Ah, but that's the thing. He didn't go straight through the shop. - No? - He came all the way over here to get the popping book. Why not some jewellery or a vase? They're much closer. Far more valuable. He can't know much about antiques. No. Unless... he knows something about that book that we don't.
