The Mind Palace is the official adult colouring book for the BBC series Sherlock, starring Benedict Cumberbatch and Martin Freeman. The illustrations were drawn by Mike Collins, and the book is 80 pages in length.

The Mind Palace is a reference to what Sherlock uses to solve mysteries. It helps him concentrate and remember small details which may or may not be linked, and I love that they chose to name the book after that.

The book itself has incredibly detailed drawings which are quite similar to a mosaic piece of art. This makes it a challenge to colour in each small detail with care, and it takes a great deal of time and effort just to complete onr page as the pages are quite large. This gives the book great value since you won't be able to simply rush right through it. It's also a good distraction for the mind, as you have to focus on the task at hand, instead of any outside interference, in order to achieve the result you want.

The book contains scenes from the first three seasons, or nine cases, from the show. Some of the pages literally look like some of my favourite scenes, whereas others are character portraits and others still are intricate patterns. One section is drawn to look like the wallpaper in 221b Baker Street, and let me tell you, it took ages to finish!

The pages are very thick, and the paper is of good quality. I use pencil crayons when colouring, but I don't imagine that using markers would pose a problem here. I don't think it would bleed through to the other side because of the thickness, but because the illustrations are on both sides of the paper, I would still exercise caution just in case.

If you're a fan of the show and you want to do some colouring, this is the perfect choice. The illustrator has done colouring books for other shows and films, so if you like his work, you can find more books with his drawings to colour.
