He Shall Thunder in the Sky (also published as Thunder in the Sky) is the 12th in a series of historical mystery novels by Elizabeth Peters, first published in 2000, and featuring fictional archaeologist and sleuth Amelia Peabody. The story is set in the 1914–15 dig season in Egypt.
Plot
The novel opens with a Prologue, relating a boy of 14 coming home in a carriage in the snow, passing a woman and her son. The carriage continues to the house, where his widowed mother awaits. She tells him the woman was his late father’s mistress, the boy, their son. His mother refuses to help them, and orders her son locked in his room so that he cannot help them.
The scene shifts to autumn 1914, after the outbreak of war, when women give out white feathers for cowardice to any young man not in uniform, like Ramses. Emerson’s annual archaeology trip is not stopped by the war, though the Suez Canal, quite close to the dig site, is an immediate focus of the conflict; Britain formalized its protectorate of Egypt to strengthen its position to keep control of the canal. Ramses is working on the dig with his parents. Foster sister Nefret Forth returns from studying medicine in Switzerland, fully qualified as a physician and fully recovered from her brief and mistaken marriage. David Todros, grandson to the late Abdullah, is married to Lia, and he is a fully qualified artist and Egyptologist. The three young adults are close.
David was sent away to India, having expressed interest in Egyptian nationalism. Emerson and Amelia hope to get him back with them. Lia is in England, pregnant with their first child.
Emerson accepts a role as adviser on Egyptian affairs, with the army, continuing the dig close to Cairo, in Giza. Their house is on the west bank of the Nile.
Amelia reflects on the abrupt change in their life when little Sennia and her mother were brought to their house two years earlier, with a procurer hoping to embarrass Ramses with the child, who has the eyes of a Peabody. Cousin Percy Peabody is the father, and arranged the scene. The Emersons took her in. She remains in England, at 5 years old too young for the dig. Things are almost back to normal between Nefret, who at first distrusted Ramses regarding Sennia, and Ramses.
Percy Peabody, nephew to Amelia, was again in Cairo, with the British Egyptian army, a captain now. Ramses hates this cousin, and the feeling is mutual. Years earlier, Percy had been held for ransom in Palestine. Ramses, in his Arab garb, had rescued Percy without being recognized. Later Percy learned it had been Ramses, which caused more hatred, no gratitude.
Thomas Russell of the Cairo police tells Emerson how much he wants Wardani, leader of the Egyptian nationalists, to hold his followers at bay, turn himself in, to delay civil disturbance in Cairo while control of the Suez Canal was still threatened. He asks them, Emerson, Amelia and Nefret, to assist. They call Wardani out, tell him to escape, while Emerson misdirects the police officers. They soon meet Ramses, who had turned Russell down.
As the Emersons witness Wardani, Ramses has already taken over that role; the real Wardani was taken, sent to India in exchange for David, who can appear as Ramses when needed. Amelia feels foolish that she had not recognized her son in disguise. He helps the war effort in that way. Nefret is kept unaware of this work by Ramses.
Called away from the dig to rescue a girl stuck climbing a tall pyramid, Ramses and Emerson meet Melinda “Molly” Hamilton and her governess. She is an orphan, under the charge of her uncle Hamilton posted to Cairo.
Ramses realizes one of the loyal nationalists under him as Wardani is trying to kill him and is a spy for the German-Turk alliance. Amelia tells this to Russell, wanting his unit to seize the spy. The plan for getting Farouk out on the street for police capture fails, and Emerson agrees to a deal with a delay of two days. Three days later, Russell tells Emerson and Ramses that Farouk’s body was found; he was murdered by the Turks. They never learn the name of Farouk’s contact.
Emerson and Ramses trek east toward a relic in the desert, first reporting to the British military post where Hamilton is stationed. At the relic, gunshot hits Emerson’s horse. The shots continue; the two find a more protected spot and wait. Their attacker approaches, dressed in British uniform, speaking almost colloquial English. Emerson talks with him then jumps on him. Ramses disarms him, asks his name. Seeing he is trapped, the young German soldier commits suicide.
