A fatal slip on the toy car that his son had left in the bathroom, and Victor Tourterelle is despatched straight to the other side of the mirror, to the beautiful world of a chalk desert, under a sky as black as ink. No noise, not a soul. In his new state, Victor delights at still being fully aware, even more clearly than on earth. But as for his body, it is only bones. Distraught, the dead man does not imagine that he is at the dawn of the wildest adventure that anyone has ever attempted once he has landed in the other world.
