A brace of reissued romances which the Queen of Crime did well to conceal under a pseudonym. The Burden (1956) is a chiffon pie which holds its shape; Giants' Bread (1930) fails early on, an overheated rendering of the career of unstrung Vernon, a composer of angst-ful music who weds flighty Nell, attracts exotic-but-honest Jane, and after two ""deaths"" and resurrections, saves the wrong one from drowning. In The Burden, guilt-ridden Laura, whose possessive love for her younger sister leads her to a shocking and merciless Act, at last faces the consequences of her own life. Dated dalliances from an acerebral Christie.
