More 

 Dolly 

 Dialogues 



By 



ANTHONY HOPE 



Dainty, adorable Dolly is 

 born again! Rarely does an 

 author make a success so sudden, 

 so complete, and so permanent 

 as that of Anthony Hope in the 

 "Dolly Dialogues." Now the 

 writer has returned to his al- 

 legiance, and in "More Dollv 

 Dialogues" we find that delight- 

 ful woman and her clever inter- 

 locutor — not more, for that were 

 impossible — but just as brilliant, 

 justaselliptic, just as spontaneous, 

 just as piquant, as amusing and 

 demure, — in a word, just as 

 fascinating as of old. The series 

 will be illustrated throughout by 

 Howard Chandler Christy, a 

 master in depicting society scenes.
