  The classical and quantum properties of a new solution obtained in $2+1$%
-dimensional gravity coupled with a real scalar field is analyzed in detail.
The considered new solution is a one-parameter generalization of a previously
known solution. We investigate the solution classically by calculating exact
null and null circular geodesics which correspond to a typical particle probe
of the correspondsing black hole spacetime. The solution admitting naked
singularity is investigated within the context of quantum mechanics. The
timelike naked singularity is probed with spin-zero and spin-half quantum
particles. We show that the curvature singularity in the new solution is
stronger and hence in general the spacetime remains quantum singular with
respect to a quantum particle probe.
