  We study the resonant sequential two-photon ionization of neutral atoms by a
combination of twisted- and plane-wave light within a fully relativistic
framework. In particular, the ionization of an isotropic ensemble of neutral
sodium atoms ($Z = 11$) from their ground $3^{2}S_{1/2}$ state via the
$3^{2}P_{3/2}$ level is considered. We investigate in details the influence of
the kinematic parameters of incoming twisted radiation on the photoelectron
angular distribution and the circular dichroism. Moreover we study the
influence of the geometry of the process on these quantities. This is performed
by changing the propagation directions of the incoming twisted and plane-wave
light. It is found that the dependence on the kinematic parameters of the
twisted photon is the strongest if the plane-wave and twisted light beams are
perpendicular to each other.
