London, 1947: it's freezing winter in the shabby, bomb-damaged city. Young socialite Dinah Wentworth, a bright, innocent newcomer to the Fitzrovia scene, becomes embroiled in a dark scandal when she discovers the corpse of surrealist artist Titus Mavor. Not wanting to explain her reasons for being at Mavor's flat that evening, she decides against reporting her grim discovery to the police. But her silence has terrible consequences. Dinah's husband's friend, Colin Harris, is linked to the crime and arrested on suspicion of murder. Dinah realises someone is trying to frame him and knows she must uncover the real villain before Harris is hanged. Set against the background of the Cold War, post-war shortages, and the struggling British film industry, Elizabeth Wilson's elegant noir vividly evokes the fashions and politics of a bohemian community flourishing in defiance of austerity. The Twilight Hour is a riveting thriller with a corkscrew twist.

An electronic calculator with trigonometric functions can be used to compute times of sunrise, sunset, or twilight, or time of desired illumination at any location in mountainous terrain. The method is more convenient and versatile, and less cumbersome than using tables. Latitude, longitude, elevation, day of the year (1 to 366), and slope to the horizon at the azimuth of the sun at sunrise and sunset are necessary for the computations. The effects of elevation of the observation point and blocking of the sun's radiation by terrain surrounding tlie observation point are included in the computations.
