This light comedy has little more to it than a gratifying triumph over the whims of a fussy old lady but there are concurrent doings that trip the fantastic in a pleasurable sort of way. Mary, Ann, Christopher, Timothy and all the other children of Pudding Street dislike Miss Pursey who shuts her house and lot. Then Ann, the youngest, discovers Miss Pursey is a button collector and a consequent bribe opens the lot periodically to the kids. Then, for buttons, Miss Pursey decides to go off to Zanzibar, and in her absence Captain Happy buys 121 and lets the children run freely. Small plots and counterplots foil Miss Pursey's attempt to buy it back again when she returns from Zanzibar.
