The Distance Between Sirens

Dr Kola Adebayo trusts evidence. He has built a career protecting clinical research from error, pressure and convenient lies. So when he sees a man on a Manchester-bound train who is officially dead, Kola knows exactly how impossible-and dangerous-the sighting is.

The man is connected to Trial Meridian, a programme already stained by unexplained deaths and altered safety data. He is also connected to Zara Bello, the brilliant documentary producer investigating what happened to her brother. Zara has access Kola lacks, instincts he distrusts and secrets she believes she has the right to keep.

Their investigation moves through elite galas, compromised institutions and a seventy-two-hour race from London to Lagos. Kola can box, but he is no operative; Zara can shape a narrative, but she cannot control what truth will do to her family. Every discovery draws them closer. Every omission threatens the trust their desire has made unavoidable.

To prevent a medical programme built on buried casualties from expanding across West Africa, they will need more than one witness or one stolen file. They will need patients, audit trails, courage-and the willingness to surrender the versions of themselves that danger once made necessary.

The Distance Between Sirens is a sophisticated romantic action thriller about evidence, accountability and an adult love strong enough to face daylight.
