Anthony Trollope 
Thackeray 

If you want to learn a little more about William Thackeray, both as a person and of his works generally, this monograph will certainly satisfy you. Yet, what may astonish you is the overwhelming capacity of Trollope’s mind, as well as the vastness of its repository, for he dissects many of his friend’s works in such a meticulous way that would imply that he, Trollope, did nothing else in his whole existence other than study Thackeray’s diverse writings as well as every subject, personage or circumstance thereof treated or simply alluded to (even the misheard brogue of the Irish, often scoffed at, is analysed!)
