This novel alternates its moments of sensational action with long passages evoking with humour, precision, and pathos the ordinary in family life in several strata of the middle classes: nouveaux riches, newly poor, and just risen from the working class. It begins with the insufferably condescending New Year hospitality extended by Mrs Lockwood (wife of a prosperous lawyer, mother of three spoiled girls) to Mrs Hunter (poverty-stricken widow of an architect, mother of three orphan children: Molly, Martin, and Thea). Mrs Lockwood bestows one article of fashionable clothing, and quantities of party food which would have had to be thrown out if it had not been given to the Hunters. It is the story's eventual protagonist, Thea, who is most strongly drawn by the luxury of the Lockwood house, and most enraged by the crassness of Mrs Lockwood and by her own mother's humble gratitude. As time goes on, Mr Lockwood considers he is doing the Hunters a succession of favours. He looks at business papers, admonishes the struggling widow to greater economy, and later places Molly and Martin, when each leaves school at fifteen, in jobs they hate (as a governess and bank clerk respectively) and which sap their health and spirits. Unknown to any of them, Mr Lockwood has also swindled them. The deceased Richard Hunter had borrowed three hundred pounds from him and paid it back. Lockwood concealed the repayment, and accepted from the grieving widow the freehold of a paddock between the two families' properties, which he particularly wanted and whose actual cash value (probably far more than three hundred pounds) Mrs Hunter never wondered about.
