In Christopher Reid's marvellous new collection, a schoolboy furtively and thrillingly drops a marble through the top of his desk so that it makes its way in darkness along a complicated chute of books, rulers and rubbish, only to emerge from a hole in the base and be caught deftly in his other hand. The poem is titled 'Homeric' and might serve as a clue to the mood and construction of the collection in general, where the poet, now in his seventies, seeks to track down and commune with his much younger self. It is an investigation that tests Wordsworth's 'the Child is father of the Man' by contriving a series of transtemporal encounters between two selves who may now, conceivably, begin to understand each other.
