six months in a glove box
Car glove boxes are similar to womens’ handbags when it comes to accumulating objects.
In the case of Mr Francis, the Rubaiyat was in his glovebox for about six months and during that time any one of the car’s occupants might have used it for noting down a telephone number.
This possibility would have been considered by the investigating police, and with Francis being a man of some influence so might have been one or two of his passengers.
This weakens the argument that has Jessica and SM directly connected and leaves it only with her reaction to seeing the bust.
