I cannot remember another title's book so descriptive as this "No Loose End".
This is the fourth and last book in Blake Larsen's series; Jack Slater confirmed that in the "author's notes" at the end of the book explaining we should not expect another Blake's book.
From the first book in the series, death of Blake's parents is brought behind the scene with little pills of "somebody" related to that death closing to Balke in the second and third book.
This is finly the main plot in the ourth book and it didn't deceived me keeping my attention fully into the book.
On one hand I feel pitty Blake's novels are over but, on the other hand, as no loose ends remains there, I've had a frash full closure for this series I really enjoyed it a lot.
