The next day dawns crisp and sharp and you meet at the station, heading towards Tynemouth along the banks of the Tyne. Tynemouth itself is quite a genteel, well-healed village that is on the very mouth of the river where it meets the North Sea. It has a ruined abbey and various monuments as well as traditional English seaside resort-type attractions.
On the train, with plenty of time to do it, Brindleton attempts to finagle the diary he found open. He manages to do so without breaking it. However the pages are filled with strange pencil scratchings - triangles and other geometric shapes, with dots and lines. It's clearly been written in code.
Any research conducted in the library at The Grey Society has not revealed a great deal about Kabbalah. However, it does reveal that there is way of representing the tree of life as having 11 Sephira rather than 10.
