10 Downing Street is presented as both a working government headquarters and a familiar domestic building whose calm surfaces persist as the Sudeten crisis sharpens. Through Hugh Legat’s movement between its lobby, offices and Cabinet Room, the novel makes the building a practical stage for political decisions, contested information and the preparations for Neville Chamberlain’s journey to Munich.

Architecture and Arrival

Four months into his secondment from the Foreign Office, Legat still experiences each entry as if he were stepping into an unfashionable gentlemen’s club. The lobby’s black-and-white tiles, Pompeian-red walls, brass lantern, slowly ticking grandfather clock and cast-iron umbrella stand give the place a settled, ceremonial air. A telephone rings somewhere deeper in the building, while the doorkeeper returns to his leather coachman’s seat and the Evening Standard. The details establish a routine that the accumulating crisis has not yet visibly disturbed.

In the passage leading towards the back of the house, Legat checks his appearance in a mirror, straightens his tie and smooths his hair before turning towards the closed Cabinet Room door. Sir Horace Wilson’s office is closed too; the corridor to the Prime Minister’s Private Secretaries lies to the other side. The Georgian house seems imperturbably calm, but its doors mark the boundaries of offices where access to the government’s decisions is increasingly consequential.

Offices, Hierarchy and Information

Legat shares the smallest office with Miss Watson, whose desk is nearly hidden behind piles of folders. She prepares answers to Parliamentary questions and has worked in Downing Street since the premiership of Lloyd George. Her dense paper barricade makes visible the routine clerical labour behind the government’s public business. From this crowded room, Legat learns that Osmund Somers Cleverly is looking for him and that Neville Chamberlain is meeting the Big Three in the Cabinet Room.

Cleverly’s office, on the north-facing side of the house overlooking the Downing Street garden, is shaded by unpruned trees that screen Horse Guards Parade. At a moment of mounting emergency, Cleverly switches on a lamp and rebukes Legat for allowing family obligations to intrude on official work. He then assigns him to arrange for the BBC to set up its apparatus in the Cabinet Room for Chamberlain’s broadcast to the nation. The setting links a private office’s dimness and discipline to the machinery of public communication: decisions made within the house are about to be carried beyond it.

The building is also a place where records, and the absence of records, matter. After Legat leaves a meeting, Cleverly appears near the Cabinet Room and asks what happened to the minute of the Prime Minister’s meeting with the Chiefs of Staff. Legat says Chamberlain did not want the meeting recorded; Cleverly then asks what Legat is carrying. The exchange turns an ordinary corridor into a point of scrutiny, where movement through the house can expose questions about who knows what and which events will enter the official record.

The Cabinet Room and Political Conflict

The Cabinet Room is the setting for more than administrative coordination. As Chamberlain reads Hitler’s letter, Lord Halifax argues against sending Sir Horace Wilson’s proposed telegram demanding that the Czechs surrender their territory immediately under threat of force. Halifax warns that the telegram would amount to capitulation, that the House of Commons would not accept it, and that Britain cannot guarantee German forces would stop at the Sudetenland rather than occupy the whole country. His intervention changes the atmosphere around the table: ministers lean in, recognizing that a senior figure has openly broken with the proposal.

The room’s significance lies in the contrast between its enclosure and the scale of the consequences being weighed there. The government’s deliberations concern a demand that could bring war, while the Cabinet Room remains one of several rooms behind closed doors in a seemingly composed Georgian house. Within that space, policy is not simply announced from above: competing judgments about coercion, responsibility and the risks of refusal meet at the same table.

Departure from Downing Street

At nine o’clock, Cleverly gathers the junior Private Secretaries in his office: Legat, Cecil Syers and Miss Watson. He asks them to return by seven-thirty the next morning to give the Prime Minister a send-off before the drive to Heston Aerodrome. Chamberlain’s party is to travel to Munich in two aircraft. Cleverly first selects Syers to accompany the Prime Minister, but the arrangements change: after Colonel Menzies requests Legat’s inclusion, Cleverly reluctantly authorizes him to go, entrusting him with Chamberlain’s dispatch boxes and the keys to them.

The departure turns the house’s official routine into a visible procession. Chamberlain comes down from his flat with Mrs Chamberlain, Wilson, Lord Dunglass and Cleverly; detectives carry his luggage, including the two red boxes of official papers. Downing Street staff applaud discreetly as Chamberlain embraces his wife, raises his hat and leaves in the rain. Legat follows last with the boxes and his suitcase, then joins the convoy in the fourth car. The journey begins at the building’s front door, carrying its documents and staff out through Whitehall and towards the conference that will determine the immediate course of the crisis.
