Phoebe Atwood Taylor writing as Alice Tilton: The Hollow Chest (1988)

From the Publisher:
"The problems which confront me at the moment," Leonidas said, "are many and varied." Indeed. For starters, Merideth Academy's Fifth Form annual egg fling gets out of control and a boy is missing. Meanwhile, Leonidas' home has been ransacked and a strange girl, bound and gagged, is left in his bed -- a girl who promptly disappears.

Next a summons from the missing boy's guardian brings Leonidas to a suburban street corner where he is confronted with a large cumbersome chest and the corpse of one Woodrow Yerkes, neighbor and president of the East Coast Trust Company. And this is only the beginning of the wildest Witherall romp ever.

PHOEBE ATWOOD TAYLOR (1909-1976) lived in Boston and Cape Cod for most of her life. In addition to the Leonidas Witherall series, she was the author of the Asey Mayo mysteries, and, writing as "Freeman Dana," Murder at the New York World's Fair.
