"The Welcome Centre" is a chilling modern retelling of Sweeney Todd set in contemporary London, where charity becomes a mask for systematic murder. The story follows Marcus Lovett, a disgraced NHS surgeon who transforms a Victorian building in Bermondsey into what appears to be a beacon of hope for homeless youth aged 16-25.

Beginning in early 2020, just before the COVID-19 pandemic, the Welcome Centre presents itself as a privately funded facility offering genuine support to London's most vulnerable young people. Marcus, stripped of his medical license after a fatal surgical error caused by substance abuse, partners with Eleanor Blackwood, a former crematorium manager, and Dr. Sarah Chen, an addicted surgeon, to create an elaborate facade hiding a sophisticated organ trafficking operation.

The pandemic provides perfect cover for their crimes. With social services overwhelmed and oversight reduced, the Centre systematically identifies residents with valuable organs, murders them in a basement surgical suite, and sells their organs to international buyers for millions of pounds. Bodies are disposed of through corrupt crematorium contacts, leaving no trace of the victims.

Seventeen-year-old Lily Morrison becomes suspicious when residents repeatedly disappear without explanation. Her investigation uncovers financial records proving the organ sales, but her discovery puts her in mortal danger. Meanwhile, the arrival of Sarah Morrison, whose aunt Kate is a Metropolitan Police detective, creates an unexpected complication for the operation.

As Lily faces imminent death in Dr. Chen's surgical suite, Sarah's desperate phone call to her aunt triggers an armed police response. The dramatic rescue exposes one of Britain's most shocking criminal enterprises, revealing that 73 young people had been murdered over 14 months.

The story follows the investigation, trial, and aftermath, exploring themes of exploitation, societal failure to protect the vulnerable.
