At 7.25 as Saskia is asking homeless people about the dead man, a rather conservatively-dressed hooker can be seen in the background in a black and purple dress and low heels.
A real hooker would be more likely to dress like Annelies lookalike, @Dolly_Dom, ( @MissBlackbeaut4 on twitter) wearing stockings, suspenders, low tops, short skirts and 5 inch heeled thigh boots rather than looking as though she is an office girl on her lunch break.
