This is the first significant study of the entrepreneurial society created by the Welsh coal boom (most books up to now having concentrated upon the workers and the unions). Using the Porth-Pontypridd area as its example, it looks closely at the networks of power created by the second-generation middle classes of the Valleys towns, and at the often hair-raising business methods that they used. Close examination of individuals, and of family groups, gives a vivid sense of the reality of the relationships and contacts, and of the nature of the society in which they moved.
