The ground floor of Selfridge’s has been transformed into a backdrop for filming a silent movie, Double Trouble, starring the Dolly Sisters and famous actor Bumby Wallace. Harry is delighted to be doing what he does best: causing ripples of excitement throughout London as the public gathers to watch. Young Meryl even has a small part in the movie, and Grove is proud as punch. But the movie’s director is tearing his hair out due to the Dolly Sisters’ diva-like behaviour, which Harry has to manage hands-on. The Dolly Sisters keep causing delays in filming – delays that cost Harry money.
