Book excerpt: A guide to the hidden workings of plays and the trade secrets that govern their writing - by the acclaimed playwright Steve Waters. Drawing on a wide range of drama, both historical and modern, Waters takes the reader through the key elements of dramatic writing - scenes, acts, space, time, characters, language and images - to show how a play is more than the sum of its parts, with as much inner vitality as a living organism. Almost uniquely amongst accounts of playwriting, Waters' book looks at the ways in which good plays move their audiences, generating powerful emotional responses that often defy conventional analysis. The Secret Life of Plays is for playwrights at any stage of their career, and will inspire and inform drama students as well as working actors and directors. Most of all it is for anyone who has ever laughed or cried in the theatre - and wants to know why. 'Theatre is a live medium, about bodies, sweat and feeling, even if it is informed by ideas and reason. How a thing composed of words manages to carry within it the currents of energy that generate that impression of life is what I want to explore...' Steve Waters 'Steve Waters' book is like his plays: clear, elegant and stimulating throughout' David Edgar
