Postman have certainly changed from how they used to be back in my day. Postman Pat would never steam open people's letters. 
 Not even privatisation has sunk good old Royal Mail to those lows... But Bilodo (so hard not to type 'Dildo' but that is NOT his name - repeat to self, M - that is NOT his name) is no Postman Pat. In fact, he's a creepy 'One Hour Photo' type. 
 Or is he..? I won't give away the 'twist', but I didn't see that one coming. The story came good on its Asian themes and by the end felt like a Japanese novel (it's French-Canadian) and earned itself an extra star. One to read again, and ponder over. Thank you, Dildo. I mean, Bilodo. *cough*
