Escorted back to HMP Bronzefield on Monday evening, Constance Marten was greeted by the noise of her fellow inmates banging on their cell doors.
The taunting reception came after news had filtered through to the jail that she had been handed a 14-year sentence earlier that day for killing her baby.
Behind bars, as in wider society, those who commit such crimes are particularly despised. As such, sources at the prison say she will be placed under close surveillance to ensure her safety. Yet so far she has chosen to keep herself isolated.
Although she shares the unit with other high-profile child killers including Lucy Letby and Beinash Batool, who is serving a 33-year sentence for the murder of her ten-year-old stepdaughter Sara Sharif, Marten has refused to socialise with them.
She rarely takes part in educational activities or workshops, preferring to spend lengthy periods in her cell.
