About His Person by Simon Armitage

The title of this poem has double meanings, as 'About His Person' is a term used by police when a dead body is found (and this suggests that he is dead), yet it could also mean what he has on him.
In the first stanza, the poet uses precision when he gives us a detailed account of the amount of change found in his pocket or wallet etc. The quote 'its date of expiry' suggests that the body was found on the same date that was written on the library card.
In the second stanza, the postcard is described as 'stamped... but franked', meaning it has been sent to him but is unusually blank. This leaves the reader asking questions about who sent it and why they would send a blank postcard.
The pocket diary was found 'slashed with a pencil' in the third stanza over the course of almost a month, implying that the man of which the body belonged to had been planning to go away, or had just not been busy.
The fifth stanza states that he has 'A final demand in his own hand'. This could give the reader the thought of a bill or debt that has been unpayed. 'in his own hand' could suggest that he is either holding it or that it is written in his own handwriting.
The poet has only two lines to each stanza in the poem, I think this is so that small pieces of mysterious information are read at a time, each leaving the reader time to think about the unanswered questions.
