He reached Algeria in December that year but, after several failed attempts to get from there to London, returned to Antibes in April 1941 and got back in contact with Girard, who recruited him into CARTE as his second in command under the codename Louba.

In London that July, at Orchard Court, he met SOE's chiefs (Maurice Buckmaster, Nicholas Bodington, and probably Charles Hambro and Colin Gubbins).

They were landed at Cap d'Antibes on the night of 29/30 July 1942 from the boat Seadog, with agents Harry Despaigne (MAGNOLIA) and Yvonne Rudellat (SOAPTREE), and on 12 September Bodington returned to England to make a highly favourable report on CARTE.

The Germans having occupied the previously unoccupied zone of France, SOE wanted to review its plans with CARTE and demanded in a message on 12 November (received via Adolphe Rabinovitch, radio operator of the SPINDLE network) that Girard return to London.

Frager and Churchill were picked up by Lysander on the night of 23/24 March (landing at Estrées-Saint-Denis near Compiègne, piloted by Hugh Verity, flying in Francis Cammaerts and Georges Duboudin) and joined Girard in London.

On the night of 14/15 April 1943 Frager was returned to France by Lysander (BRONCHITE drop zone, near Tours) and welcomed back by Henri Déricourt (GILBERT).

He flew to London again on 20/21 October 1943 (in a Hudson, from the ACHILLE landing strip near Angers), but his pick-up had been organised by Déricourt, now under Sicherheitsdienst surveillance.

His visit was facilitated by Gilbert, who once more enjoyed the British's confidence and had become head of all personnel on the ground for secret flights and landings by SOE's French section.

Only Paul's determination, threatening to use his pistol, prevented Roger from being kidnapped and transferred to London by force.On 29 February 1944 Frager was returned to France at Beg-an-Fry near Morlaix, under the codename Jean-Marie.
