Question on the chronology between the Adept and Templar series

[Bynw]

Katherine replies: "There is, indeed, a nebulous thread that ties these books together. Chronologically, I'd say they line up as follows:THE TEMPLE AND THE STONE
THE TEMPLE AND THE CROWN

LAMMAS NIGHT

The five Adept books

"The next Adept book, when we get the go-ahead to write it, will pick up not only as Adept VI, but will also show action in flash-back that covers Philippa's work with John Graham, thus falling between LAMMAS NIGHT and THE ADEPT.

"In addition, I believe that Richard of Kilsaren, who appears in SAINT PATRICK'S GARGOYLE, is also mentioned in THE TEMPLE AND THE CROWN."
