  We present Suzaku observations of the Abell 98 (A98) triple galaxy cluster
system and the purported intercluster filament. The three subclusters are
expected to lie along a large scale cosmic filament. With partial azimuthal
coverage of the northernmost cluster, we find that the inferred entropy profile
of this relatively low mass cluster ($kT \approx 2.8$ keV) adheres to
expectations from models of self-similar pure gravitational collapse in the
region of the virial radius. There is evidence of extended structure beyond
$r_{200}$ to the north of the northernmost cluster, along the merger axis, with
properties consistent with what is expected for the warm-hot intergalacitc
medium (WHIM; $kT = 0.11_{-0.02}^{+0.01}$ keV, $n_e = {7.6 \times
10^{-5}}^{+3.6 \times 10^{-5}}_{-3.6 \times 10^{-5}}$~cm$^{-3}$). No such
emission is detected at the same radius in regions away from the merger axis,
consistent with the expectation that the merger axis of this triple system lies
along a large scale cosmic filament. In the bridge region between A98N and
A98S, there is evidence of filamentary emission at the $2.2\sigma$ level, as
well as a tentative detection of cool gas ($kT \sim 1$ keV). The entropy
profile of this intercluster filament suggests that the A98 system is most
likely aligned closer to the plane of the sky rather than along the line of
sight. The structure to the north of the system, as well as in between A98N and
A98S is indicative that the clusters are connected to a larger-scale structure
spanning at least 4 Mpc.
