We show that |$1+3/\sqrt{2}$| is a point of the Lagrange spectrum |$L$| that is accumulated by a sequence of elements of the complement |$M\!\setminus\! L$| of the Lagrange spectrum in the Markov spectrum |$M$|. In particular, |$M\!\setminus\! L$| is not a closed subset of |$\mathbb{R}$| , so that a question by T. Bousch has a negative answer.
