It is proved that, if X (pi) under right arrow T is a proper holomorph
ic map with one-dimensional fibers and (X) over tilde (pi) under right
arrow X a covering map, a point t is an element of T has a neighbourh
ood U such that pi(-1)(pi(-1)(U)) is holomorphically convex if and onl
y if pi(-1)(pi(-1)(t)) is holomorphically convex.
