This collection contains letters that are instigated by the inquiries of Mr. Charles Perry Gould, and his desire to have Llewelyn Powys write an introduction for the upcoming reprint of The Simple Cobbler of Agawam. It contains the initial contact, the deal under which Powys writes the introduction, and also what happens to his writings after Powys' death. Sometimes in his letters to Mr. Gould, Llewelyn encloses postcards of Davos, Switzerland, as well as a picture of the author himself.

This collection contains letters from Theodore F. (T. F.) Powys to his sister, Lucy Penny, and his friend, the writer Valentine Ackland.
