The Second Caller

Sixteen years ago, an emergency call sent the police to No. 17 Haining Lane.

Sixteen years later, another call comes from the same address.

What makes it unsettling is that the caller seems to know which door the police will knock on by mistake.

As the investigation deepens, an ordinary aging apartment building begins to reveal things that do not add up: eight seconds missing from a recording, traces that have vanished from surveillance footage, conflicting witness statements, and five steps between the fourth and fifth floors that should not exist.

Following the trail left by the second caller, Chen Yan and Gu Wen discover that they are dealing with more than an old case. Sixteen years ago, someone went unheard. Someone chose to remain silent. And someone has been waiting all this time for that door to be knocked on again.

When the evidence finally leads them back to one place, they face a harder question:

If the truth arrives sixteen years late, can it still change anything?

The Second Caller is a contemporary mystery and social suspense novel about surveillance, domestic violence, silence, and the pursuit of justice, unfolding through two emergency calls made sixteen years apart.
