Not as spectacular in situation as Cruise of the Maiden Castle perhaps, but every bit as delightful, this story of more Warner adventures makes sparkling reading. Alan, Joan and Christopher Warner, combining juvenile inventiveness with a sturdy self-sufficiency, are involved in a money-making scheme to rescue a mistreated wagon horse. Their primary fund is smashed with the greenhouse when they are called upon by their father to make reparations for their garden escapade, and a half-hearted attempt is made to raise money by household chores. However, more unorthodox and adventurous methods present themselves in the form of flower-picking with the mysterious ""moocher"" Pritchard, a deserted house and hidden treasure. The Warners are real children -- imaginative, plotting and vigorous. Adults in this story, too, are more than shadows -- the irascible gardener Potter, gruff, hearty Miss Gockett with her farm for old horses, the earthy Pritchards, and an understanding set of parents. And cousin Benjamin is the most horrid little boy we have ever seen in juvenile fiction who will make the reader shudder in recognition or remembrance. An excellent adventure story with plenty of glimpses of the fresh English countryside.
