The Introduction contains a discussion of previous criticism of Tourneur's work and an account of the methods followed in this study. This is followed by a detailed analysis of the style of The Revenger's Tragedy, considered in isolation, and a more cursory examination of the style of The Atheist's Tragedy considered in relation to the earlier play. The final chapter contains some new observations and evidence bearing on the authorship problem. The first three appendices relate solely to The Revenger's Tragedy, the fourth to both plays. The whole work is based on a concordance which I have compiled to the plays.
