This is an excellent monograph, though being in the 'Studies in European History' series it does presuppose some previous knowledge of the Revolution and its main events and personalities. But if you do have that background knowledge I thought it was a perfect example of a clearly written, well-argued account of the Terror, its origins, course and decline , including quite a lot of interesting detail about the events and development of it, and in particular the debates of historians of different persuasions around it. There is also a detailed bibliography.
If, like me, you find this a fascinating period of history, you will, I think. gain a great deal from this little book.
