In LATH we find that "McNab's" first wife, Iris, died in April 23, 1930.
She was killed by Lieutenant Starov (Wladimir Blagidze).
btw: I found a curious construction by LATH's disoriented
hero: "The left side of my head
was now a bowling alley of pain. On the other side an inane
baby was
staring at me across its mother's shoulder over
the back of the seat in front of
me."
