Phone

For the four characters at the heart of Will Self's brilliantly acute novel of our times the five hundred-quid worry bead in their pocket may be both a blessing and a curse. For elderly Dr Zachary Busner it is a mysterious object - 'NO CALLER ID - How should this be interpreted? Is it that the caller is devoid of an identity due to some psychological or physical trauma?' - but also it's his life line to his autistic grandson Ben, whose own connection with technology is, in turn, a vital one.
