This was terrible, and failed to amuse me.
Many of the letters seemed far too fantastical to believe that they had actually been sent and replied to. Ravenscroft tried too hard to be hilarious, and failed miserably to get even a tiny smile from me.
Also, I'm not sure if I'm being a bit of a prude here, but I found some of the letters to be quite racist and patronising. I understand it was all in jest, but surely there are better ways to incite laughter in someone than to mock their mistakes when using a language that isn't their mother tongue?
I had planned to read another of Ravenscroft's letter-based novels, but have decided against it. Please avoid him at all costs if you value your time.
