All Clear

But if he had, there should be more discrepancies than just a siren going off when it shouldn’t have. And Mike was right, there were all sorts of instances in history when an action which should have had a major effect had been counteracted by something else, like the Verlaine-poem invasion signal. Or the appearance of

“Omaha” and “Overlord” in the Herald’s crossword puzzle, which hadn’t affected the invasion after all.

But that was also an example of how a single small action could have tremendous consequences. A few words in a crossword puzzle had nearly derailed an invasion involving years of careful planning and two million men. If D-Day had had to be delayed, the invasion’s location would almost certainly have leaked out, and Rommel’s tanks would have been waiting for the invasion troops at Normandy. And all because of a bit of carelessness and a teenaged boy. “For want of a nail …”

So what sort of impact could the combined actions of Marjorie and Hardy, and Gerald’s and now Mike’s wandering around the place where the most important secret of the war was being kept have? If Mike got there. Just because he’d gone to Dunkirk didn’t mean he’d be allowed to reach Bletchley Park.

She gave the retrieval team another half hour to show and then went back to Mrs. Rickett’s to see if Mike had phoned. He hadn’t, and by the time Eileen returned, there’d still been no word from him. “Did you find out what the Hodbins were up to?” Polly asked her.

“No, no one was there,” Eileen said, frowning. “I had to slide the map under the door. Did Mike ring up?”

“No, not yet. His train was likely delayed by a troop train or something.”

But she must not have succeeded in hiding her anxiety, because Eileen asked, “No trains were bombed today, were they?”

“No.” Not in London.

“Was Bletchley bombed?”

“I don’t know, but there were never any casualties at Bletchley Park. Come along, it’s time for supper. One of Mrs. Rickett’s Sunday-night ‘cold collations.’ ”

Tonight it consisted of sliced tongue and nettle salad. “I’m sorry I ever got my ration card,” Eileen said when she saw it. “I can’t wait till Mike finds Gerald and we can go home. Perhaps that’s why he hasn’t rung us, because someone on the train knew where Gerald was, and he’s gone off to find him.”

But when Mike finally rang up, moments before Polly had to leave for Notting Hill Gate for rehearsal, it was only to say he’d arrived. He hadn’t even left the station yet. And he was in a hurry. He told them he’d phone them again when he knew where he was staying and rang off before Polly could warn him to be careful.

But if the problem’s an increase in slippage, then it would have prevented him from going to Bletchley Park if he could affect events. There’s nothing to worry about, she told herself, and forced herself to concentrate on the problems of the admirable Crichton and Lady Mary.

The troupe was in their final week of rehearsals, and Sir Godfrey was in a foul mood. “No, no, no!” he shouted at Viv. “You say, ‘Here comes Ernest,’ before Ernest makes his entrance! Again. From ‘Father, we thought we should never see you again.’ ”

They started through the scene again.

“No, no, no!” Sir Godfrey thundered at Mr. Dorming. “Why can’t you remember? This is a comedy, not a tragedy. At the end of Act Three you are rescued from this island.”

“By a prince?” Mrs. Brightford’s little girl Trot asked.

“No, by a ship. Or, considering the rate at which this production is progressing, by the end of the war.”

“I think it should be by a prince,” Trot said.

“Take it up with the author,” Sir Godfrey growled. “Try it again. From ‘Here comes Ern—’ ”

“Sir Godfrey,” Lila interrupted. “You keep saying it’s a comedy, but how can it be when Lady Mary and Crichton are separated at the end?”

“Yes,” Viv said, “and why can’t they be together?”

“Because he is a butler and she is a lady. You and Mary,” he said, glaring at Polly as though this was her fault, “are far too young to ever have loved someone whom, for reasons of social class or age or circumstance, you could not be with, but I assure you lovers do sometimes face insurmountable obstacles.”

“But if they didn’t have to part,” Viv said, “it would make the ending so much more romantic.”

“As I told Trot,” Sir Godfrey said dryly, “take it up with the author. Again. From the beginning. We are going to get this right if it kills me. Which it may very well

“As I told Trot,” Sir Godfrey said dryly, “take it up with the author. Again. From the beginning. We are going to get this right if it kills me. Which it may very well do. Unless the Luftwaffe gets me first.” He looked up at the ceiling. “The raids seem rather excessive tonight.”

They did, but they began and ended when they were supposed to and hit the correct targets, and there was nothing in Sir Godfrey’s Times the next night about security breaches or captured spies, though Mike hadn’t phoned again.
