A familiar form caught Robbie’s eye as he walked briskly towards the exit of Military Staff HQ. The soldier, a Lieutenant by his uniform’s insignia, was just leaving the Field Marshal’s private study wondering back out into the executive office. His brow was drawn as if he’s just received distressing news.

Robbie froze midstep. His eyes locked with the man’s through the glass panel of the office door. The Lieutenant’s frown cleared and his eyes widened with surprise. The two stared at each other for a long moment before Robbie looked away.

Continuing on his way out of the building, Robbie heard the office door open behind him. It rattle shut, but he didn’t look back. Footsteps echoed his across the marble floor  matching his all the way down the hall to the exit.

The other soldier followed Robbie up the block and down into an adjacent alleyway. His stroll was slightly hesitant as Robbie disappeared into an alcove. The soldier couldn’t see Robbie anymore, but he seemed to know what Robbie was up to. His suspicion was confirmed when smaller man reached out from a bend in the wall, pulling the Lieutenant into the secluded space.

Robbie pulled the taller man down with a hand at the back of his neck. He pressed his lips to the Lieutenant’s, surprising the man with a kiss. The other soldier didn’t jump, or push Robbie away. Quite the opposite, he embraced the smaller man and pressed him bodily against he stone wall until he was standing between Robbie legs.

Robbie’s pale fingers carded through the Lieutenant’s dark-auburn hair where it wasn’t covered by his beret. The other soldier wasn’t so considerate. He pulled off Robbie’s cap and held it in one hand while the other gripped Robbie’s dark hair to draw the younger man closer, deepening the kiss. Robbie’s lips parted under pressure and the man’s tongue ran over his bottom lip before slipping into his mouth.

Only when the air between them grew thin did they break the impassioned kiss.

The Lieutenant let out a breathy moan as they parted for air. 

“Good afternoon, Archie Hicox,” Robbie murmured as he smiled against the taller man’s lips.

“Good lord! Robbie Turner is that you, old chap?” Archie replied with a cheeky grin.

Robbie laughed as his old friend feigned surprise. “As if you didn’t just follow me for half a block, you arse,” he said while mussing the hair sticking out from under Archie’s hat in retaliation.

Archie shrugged nonchalantly. He was obviously trying to keep himself from laughing as he calmly fixed his hair. “Could have been anyone.”

“You’re going to get yourself in trouble,” Robbie whispered between gentle kisses,  ”following boys down alleyways.” 

Archie smirked and was about to respond when the sound of voices came from the mouth of the alley. Still pressed close to Robbie, he peaked around the wall. There was a group of nurses standing on the walkway having a smoking break. They were laughing amongst each other and didn’t show any sign of coming down the alley, so Archie turned his attention back to the smaller man practically pressed to his chest.

“Indeed I would,” Archie finally replied. His expression was still soft, but his tone had grown serious. It was obvious to Robbie that this wasn’t whatever witty retort he’d thought of previously. 

Robbie’s hands slid from Archie’s neck to work at straightening the man’s olive-green tie. “When were you going to write me that you were back from the front?” he asked evenly. “I’ve missed you.” 

“As I have you, but I wasn’t planning on it,” Archie confessed. He continued quickly upon receiving an doleful glance from limpid blue eyes. “What I mean to say is that I’m leaving again on the next plane back to France.”

Robbie frowned. “So soon? But you’ve only just arrived.”

“Marching orders came just before I saw you, direct from General Fenech Field Marshal Hague and the Prime Minister.” Archie sighed. “I’m joining an American team and we’re going to kill Hitler to assassinate the Kaiser.”
