We present a new analysis of the Suzaku X-ray spectrum of the Compton-thinSeyfert 2 galaxy NGC 4388. The spectrum above $\sim$2 keV can be described by aremarkably simple and rather mundane model, consisting of a uniform, neutralspherical distribution of matter, with a radial column density of $2.58 \pm0.02 \times 10^{23}$ cm$^{-2}$, and an Fe abundance of$1.102^{+0.024}_{-0.021}$ relative to solar. The model does not require anyphenomenological adjustments to self-consistently account for the low-energyextinction, the Fe K$\alpha$ and Fe K$\beta$ fluorescent emission lines, the FeK edge, and the Compton-scattered continuum from the obscuring material. Thespherical geometry is not a unique description, however, and theself-consistent, solar abundance MYTORUS model, applied with toroidal andnon-toroidal geometries, gives equally good descriptions of the data. In allcases, the key features of the spectrum are so tightly locked together that fora wide range of parameters, a relativistic disk-reflection componentcontributes no more than $\sim$2% to the net spectrum in the 2-20 keV band. Weshow that the commonly invoked explanations for weak X-ray reflection features,namely a truncated and/or very highly ionized disk, do not work for NGC 4388.If relativistically-broadened Fe K$\alpha$ lines and reflection are ubiquitousin Seyfert 1 galaxies, they should also be ubiquitous in Compton-thin Seyfert 2galaxies. The case of NGC 4388 shows the need for similar studies of moreCompton-thin AGN to ascertain whether this is true.
