The twins are living in relatively straightened circumstances, as their father has died, and get up to all kinds of mischief, while being governed by their own set of values. The children, however, have little dread of poverty, for when ever they desire a luxury, such as a bicycle, or a fur stole for their mothers Christmas present, they devise some means to raise the necessary funds, and they stop at nothing from inducing a rich great-aunt to endow a home for cats to poaching for pheasants, and no matter what they do they always come out victorious, even when it comes to making or marring marriages. The Terrible Twins is written in a bright and amusing style and the author has indeed drawn upon a vivid imagination to think of all the scrapes and escapades in which the terrible twins are involved.
