Susan Boyd worked as a dressmaker for Mrs Leach, who owned a dress stall in the local market and ran a squalid workhouse in a slum house, where several other homeless children worked and lived like slaves. When Susan tries to smuggle out a message for help, Mrs Leach punishes her by locking her in a dark cupboard. Following this, Susan pretends she has broken and starts acting as compliant toady to Mrs Leach, but she is using this to secretly help the slaves.
