I read in sci.electronics.design that John Fields wrote (in ) about 'Short message', on Mon, 21 Mar 2005:
You are right, but it does 'taper off' a bit, even though it is a genuine E C Bentley opus. The other lines are 'One can only wonder/At so grotesque a blunder'.
Actually, it should be 'of two last lines bereft'. 'With' implies that I've gone away and I haven't. Yet.(;-)
