Tatyana 'Tanya' Ilovaiskaya (left) and her dog at the dacha shared with Tyler Kent. The other three people have not been identified, though there's a strong possibility that the woman next to Tanya is the girl with whom Donald H. Nichols was involved prior to Valentina 'Valya' Scott. The girl in question didn't work for the N.K.V.D., so the Soviet authorities seized her and sent her to a labour camp.

Tatyana 'Tanya' Ilovaiskaya (centre) and Donald H. Nichols (second from the left) at the dacha shared that Tanya shared with Tyler Kent. The other three people have not been identified, though there's a strong possibility that the young woman next to Tanya is the girl with whom Donald H. Nichols was involved prior to Valentina 'Valya' Scott. The girl in question didn't work for the N.K.V.D., so the Soviet authorities seized her and sent her to a labour camp.
