In the quote from J.D. Robb's "Visions in Death," the idea of sabotage is explored through the contrast between expectation and reality. It suggests that true sabotage catches its victims off guard, relying on the element of surprise. When people are not anticipating deceit or betrayal, it becomes more effective, as they are unprepared to counteract it.

This insight highlights the vulnerability that comes with trust and the unexpected nature of malicious actions. The quote emphasizes that the essence of sabotage lies in its capacity to be unanticipated, making it all the more damaging when it occurs.
