Pub 3 offered a different kind of danger. It was quieter than the first two, more worn around the edges, and built around a narrow service passage running behind it, a route used by staff, deliveries, rubbish bins, and anyone wanting to move without being seen too clearly from the main room. At first glance it looked unimportant. In hindsight, it became one of the most useful spaces in the case.
The passage offered opportunity rather than revelation. It had multiple access points, poor light, and enough ordinary traffic to muddy certainty while still giving privacy to anyone carrying, concealing, or discarding something they did not want noticed. That mattered because Oliver did not die in a room full of witnesses. He died later, in a narrow margin of private time created by movement between venues.
After the body was found and the evening reconstructed, a fragment was recovered near the base of the passage wall. It matched the inner lining of a knife sheath or protective blade cover. The edges were torn, not cut. There was no blood on it. It was not the weapon itself, but it changed the shape of the murder. A fight that ends with a knife picked up at random looks spontaneous. A killing linked to concealment looks very different.
The implication was immediate. Someone may have arrived at the latter part of the evening already carrying the means to turn anger into something final. That did not prove long-term planning, but it did suggest readiness. All six suspects had plausible access to a kitchen knife or some way of concealing one.
The ground in the passage did not help much. Too many overlapping footprints crossed the same strip of dirt and grit. More than one person had used the route, which kept several suspects alive rather than narrowing the field.
Chloe Bennett complicated matters further. A witness saw her moving quickly through the passage, looking back over her shoulder. Later, Chloe denied entering it at all. That lie made her suspicious, but not necessarily murderous. Fear can distort the truth as easily as guilt can.
Marcus Reed gained another quiet but important detail here. A delivery driver later described seeing a man matching his build at the far end of the passage with a dark sports bag resting beside him. Aaron, meanwhile, remained awkward for a different reason. He knew these spaces too well, and his normal staff access made almost any movement plausible.
By the time the route left Pub 3, the murder had acquired a practical logic. Anger alone no longer explained the night. Opportunity had joined it.
