Not that obvious

Things are not always what they seem. Writing Thrillers, means I try to convince you to believe what I´m telling you and and the same time I try to confuse you by creating twists in the story that will knock you of your feet. What´s true and what isn´t? To learn the truth of my Thrillers you'll have to read them till the very end.
To understand the truth about the artwork (on the left) you can study it; e.g. is it really green? (Nope; there are blue spots all over). Enjoy finding the truth.
