This is what "The Group That Has No Name," also calls "The Mirror Effect."

Ms. La Roux inadvertently took a picture of Ms. Groot in Stockholm,
when this group was making a "Switch."

She was aiming for the courier, but this time,
her camera took one too many pictures.

The "group that has no name" was on a very tight schedule, everything
checked and rechecked down to the last minute - the only reason
"Nobody" would accept for an aborted mission was if and only
if they were all dead.

They just didn't count on some photographer having a Kodak Moment
at the wrong place, at the wrong time.

La Roux knew she was in trouble! As she was fleeing the scene,
an image of her face and a picture of the courier pop up on a laptop
being used by someone she didn't care to know.

The files being transmitted, to whom or where,
she was not going to hang around to find out!

She was out of breath as she slammed her back alley hotel door
shut when out of the shadows walks out three people she had
never seen before!

They threw on her bed a briefcase with 2 million Euros, they told her,
they will pay for every image on that camera.

Her work online and her presence at Didi's was well known to them,
so they won't harm her, but they could use her in the future.

(Duval had arranged this "shock session" as a method of "acquiring a recruit by subtle force")

This was part of Duval & Duval's strategy of getting closer to
Dr. Attar and her discoveries.
