Man at La Valaise

To Sacha, La Valaise and its owner, Madame Cassel, had always
been a haven. This time, she arrived to find three strangers in
residence and herself a prisoner.

What had happened to Madame Cassel? What would happen to her?

Although the mysteriously disturbing Nikolai Torlenkov said no
harm would come to her, how could she believe him when he
wouldn't let her go? And what was even more disturbing--she was no
longer sure she wanted to.
