  We study the spectrum of scalar mesons in the holographic dual of walking
technicolor, obtained by embedding D7 - anti-D7 probe branes in a certain type
IIB background. The scalar mesons arise from fluctuations of the probe
techniflavour branes and complement the (axial-)vector meson spectra that we
investigated in earlier work. By explicitly finding the spectrum of scalar
masses, we show that the nonsupersymmetric D7 - anti-D7 embedding is stable
with respect to such fluctuations. Interestingly, it turns out that the mass
splitting between the scalar and vector meson spectra is of subleading order in
a small parameter expansion. It is noteworthy that this near-degeneracy may not
be entirely due to a small amount of supersymmetry breaking and thus could
indicate the presence of some other (approximate) symmetry in the problem.
