In the interrogation room of the Greenwich Police Station, the innkeeper, Mr. Wells, sat handcuffed across the table, with Arthur and the monitoring officers, Tom and Tony, sitting on the other side.
Arthur threw a delivery slip from the London Gaslight and Charcoal Company on the table.
"The delivery slip from the London Gaslight and Charcoal Company shows that the last time gas cylinders were delivered to Wells Inn was twenty-three days ago.
We've searched all the rooms in the inn; there is only one gas cylinder, and that's the one in the room where the incident occurred.
We also consulted with authorities from the London Gaslight and Charcoal Company, who said that a gas lamp could stay lit for three hours when fully fueled, which roughly covers the lighting needed for one night.
And one gas cylinder can provide approximately thirty to forty refills of gas.
