A dead man.A forgotten investigation.And a system that can make one identity belong to someone else.Detective Inspector Daniel Tan thought he had uncovered the worst secrets behind Meridian's missing-hour case. But a mysterious file marked NORTHPOINT leads him into an older mystery dating back to 2009.A man officially declared dead continued appearing in records years after his supposed death. A hidden identity system allowed people to operate under identities that were never truly theirs. And a forgotten designation-N4-keeps appearing wherever the evidence doesn't make sense.Then Daniel discovers something closer to home.His own father's name appears inside the Northpoint system.As Daniel and Sergeant Marcus Lim reconstruct the events of September 17, 2009, they uncover a chain of altered identities, missing records, and unexplained disappearances. Rachel Ong, missing for months, may have discovered the same secret. And Adrian Voss, the man Daniel arrested in the previous investigation, may have been only one part of something much larger.Someone is still using Northpoint.Someone knows Daniel is investigating.And the deeper he goes, the harder it becomes to determine whether the evidence is revealing the truth-or deliberately leading him away from it.The Northpoint File is the second Daniel Tan Investigation, a Singapore crime mystery about identity, deception, missing records, and the dangerous gap between what happened and what the evidence says happened.
