The great detective once more demonstrates his incredible powers of deduction...
Come on in, Mr. Hingston.
I see that you used to be in the army, that you enjoy playing cricket, 7th on the batting order if I'm not mistaken, that you enjoy the poetry of William Blake...
...that you have a wife called Mavis to whom you've been married for 24 years, and that your parlour's armchairs are light blue.
For you see, I noticed your upright military bearing. You have traces of cricket ball dye on your hands, enough to suggest that you play regularly but don't always bat. You have an imprint of the word 'Tyger' on your left thumb, your ring has the engraving 'Mavis' inside, and the name of a jewellery shop which closed some 36 years ago, and you have a blue thread on your back, suggesting that were sitting on it for some time.
Also, I've been stalking you.
