18. Birdy

Six months earlier, Birdy returns to London determined to resume work and quietly verify the mysterious Thanatos letter that predicted her grandmother’s death. She books an appointment and enters a pristine Harley Street clinic run with secrecy and precision.

After a second, invasive questionnaire demanding finances, family details, and unrestricted digital access, the receptionist scans Birdy’s fingerprints and confiscates her devices. A polished, nameless “doctor” interviews Birdy on camera, revealing unsettling knowledge of her life and testing her motives for wanting an “end date.” When Birdy admits she needs to see someone before it’s too late, he greenlights the next steps.

A model-like nurse draws multiple vials of blood and collects nail, hair, and skin samples, followed by a promised scan. Birdy leaves without answers, wary yet compelled by the organization’s confidence and lack of fees.

The next day a hand-delivered, luxurious letter arrives. Birdy opens it with her dog Sunday beside her and finds her exact date of death, along with a chilling “Happy Deathday” message. The shock robs her breath but clarifies her purpose: she knows what she must do before time runs out.
